We get a lot of questions from new users about how each Menzerna paint correction product works, and what the differences are between them. While ultimately we ourselves are far from experts in paint correction, we do know this particular product line fairly well and frequently engage with members of the detailing community to learn more about the strengths and ideal combinations of product(s).
Over the years, Menzerna products have come and gone - new technologies both in coating systems and abrasive compounds have dictated what remains in the lineup. As you know, Menzerna's strength is in careful research and development, where new materials are evaluated exhaustively in repeatable, automated settings to ensure that new formulations significantly outperform in cut, resulting gloss, time to finish, total product usage, and a minimum of quality defects.
Although Menzerna got its start in solid polishing compounds almost 140 years ago, they've become and remain a leader in emulsion and liquid polish development. Diminishing abrasives - which start in highly abrasive clumps, fragment, and refine a surface in a single pass - have produced mind-blowing results via "all-in-one" type products.
The question is, what place does each product have in Menzerna's portfolio?
Menzerna differentiates between its Standard, Alternative, and Special products:
-
Standard: Lowest cost and reliable - if traditional-style - rubbing, polishing, and swirl removing compounds. Each accomplishes a single stage in the polishing process but tends to be made with older abrasive technologies. They can sometimes produce more dust or produce lower quality results than newer compounds, although Menzerna has recently released Improved Formulation(s) from their learnings with other new products.
-
Alternative: Tend to be produced for special use cases or with improved abrasive technologies. E.g., for special use with wool pads, on soft/sticky/dried out coatings, or for ultimate final gloss.
- Special: Utilize Menzerna's diminishing abrasives to accomplish multiple stages in a single process step. Effectively, they can go from an aggressive cut through to a finished result in some cases! The idea behind these is to produce the best results in the fewest steps and/or in the least total time.
How do I choose the best compound(s) for my application?
While on metal we often recommend sanding a surface to 600 or 800 grit to get the same starting point and keep your process as consistent as possible, on more sensitive surfaces like paint it's best to (until you learn the ropes) take the least aggressive approach first. When polishing your paint, just like with metal, you are abrading the surface to make it as flat as possible so light reflects in a straight line from the surface. Depth, gloss, and clarity all come from a smooth surface! When it comes to removing scratches, you need to abrade the surrounding clear coat to the base of the scratch you are trying to remove... but like with thin metal panels, you only have so much material to work with. It's often better to achieve a significant improvement in appearance than to reduce your clear coat's lifespan by 95% - or even burn through it! - chasing deep scratches. A typical clear coat has about 1.5 - 2 mils (38 - 50 microns) to work with, but this varies by make, model, year, and individual vehicle. Unless you have specifically had a vehicle painted with multiple layers of clear with the intent to wet sand and completely level any orange peel or other texture defects, we do not recommend getting overly aggressive! Heavy trucks like Peterbilt and Kenworth are likely to have more thick and scratch resistant clear coats than passenger vehicles but this isn't a hard and fast rule... nor do these approximations account for previous work done to the paint (prior buffing or re-painting)!
That all said, each compound has a certain degree of abrasion and resulting gloss. I'll highlight the manufacturer specs below - just keep in mind that Menzerna has a tendency to be conservative about their product's performance in an industry where others frequently overstate how effective their products are in real-world scenarios:
Super Heavy Cut and Heavy Cut Compounds
Menzerna heavy cut compounds remove deep scratches, spray, and heavy signs of use reliably, quickly, and thoroughly. Also ideal after deep sanding.
-
Premium Power Cut 200: although this compound is technically a replacement for Gelcoat Liquid Sanding and intended for chalky boats, faded RVs, and composites, it works extremely well on single stage industrial paints and especially hard top coats like Imron and Endura. It is, however, substantially more aggressive than the Menzerna automotive line (and basically any other automotive compound out there).
- Rated for up to P600-P800 grit sanding marks. To compare, 3M's Super Duty Rubbing Compound is the most aggressive paint compound I'm aware of which is rated for up to 1000 grit sanding marks but does not produce a high gloss.
- PPC 200 utilizes diminishing abrasives and breaks down to a Medium Cut finish, with more or less cut and gloss depending on pad choice. It also performs well on both dual-action and rotary machines like other Menzerna polishes, unlike auto-body focused compounds like the primary 3M buffing line.
-
Cut: 10/10, Gloss: 6/10 (in the gelcoat line)
-
Cut: 10/10, Gloss: 6/10 (in the gelcoat line)
-
Super Heavy Cut Compound 300 (formerly Fast Gloss 300): produces the highest cut in the automotive line but using diminishing abrasives breaks down to a Medium Cut finish. Although not generally used as a single-step polish, used with a foam pad it can easily proceed directly to a Finish polish on a soft foam pad. Depending on the paint, utilizing a more aggressive pad to cut may necessitate a second pass with SHCC 300 on a gentler pad or a Medium Cut polish prior to proceeding to finishing.
- Rated for up to 1200 grit (wool) to 1500 grit (foam) sanding marks
-
Cut: 10/10, Gloss: 6/10 (in the automotive line)
-
Cut: 10/10, Gloss: 6/10 (in the automotive line)
- Rated for up to 1200 grit (wool) to 1500 grit (foam) sanding marks
-
Heavy Cut Compound 400 (formerly Fast Gloss 400): Menzerna's former flagship compound produces an excellent combination of cut & gloss and is capable of a one-step polish on medium/hard clear coats with lighter colours; effectively it goes from a Heavy Cut to a "Finish". Used with foam, can easily proceed directly to a Finish polish on a soft foam pad where required.
- Rated for up to 1500 grit (wool) to 2000 grit (foam) sanding marks
-
Cut: 8/10, Gloss: 8/10
-
Cut: 8/10, Gloss: 8/10
- Rated for up to 1500 grit (wool) to 2000 grit (foam) sanding marks
-
Cut Force Pro Speed Compound & Polish: supplanting the older HCC 400, Menzerna's new "gold standard" flagship compound produces an even faster cut than HCC 400 and higher resulting gloss in a single step - effectively, a true "One-Step" Heavy Cut to Finish. Their former CEO confided that they pushed it during development to try to cut up to 1000 grit sanding marks efficiently, but didn't quite feel comfortable advertising as much. They have not yet published an official grit rating in their data sheets.
- Via email communication, Menznera conservatively rated Cut Force Pro for up to 1500 grit (wool) to 2000 grit (foam) sanding marks (but "faster" than HCC 400). End users sometimes note it's a touch "grabbier" than HCC 400 due to some difference in lubrication but it depends on the paint system.
- Cut 9/10, Gloss 9/10
-
Cut Force Pro and Heavy Cut 400 are our two most frequent recommendations for a quick one-step polish on heavy trucks and industrial/farm equipment.
- Via email communication, Menznera conservatively rated Cut Force Pro for up to 1500 grit (wool) to 2000 grit (foam) sanding marks (but "faster" than HCC 400). End users sometimes note it's a touch "grabbier" than HCC 400 due to some difference in lubrication but it depends on the paint system.
-
Heavy Cut 1000 (formerly Power Gloss 1000 or S34A): Menzerna's standard heavy cut compound does not utilize diminishing abrasives, instead producing a sustained cut. One downside to diminishing abrasives is that they are designed to break down and self-refine quickly, to minimize overall cycle time; as a result cutting action typically slows or stops within a few passes. HCC 1000, however, cuts... and cuts... and cuts. As a result, take care as it can behave like doing repeated passes of fresh compound with an aggressive diminishing compound!
- Technically considered a (foam) "pad" polish, this compound is rated for up to 1500 grit (foam).
- Cut 9/10, Gloss 3/10
- Technically considered a (foam) "pad" polish, this compound is rated for up to 1500 grit (foam).
-
Heavy Cut 1100 (formerly Fast Gloss 500): Menzerna's alternative line heavy cut is technically designed for use exclusively with wool pads, producing an exceptionally long working time via extra lubrication. This makes it particularly well-suited to cutting down stubborn sanding marks. It cuts less aggressively than HCC 1000 but finishes out with considerably better gloss.
- Rated for up to 1500 grit (wool). Customers also mentioned excellent results on "spider-cut pads"
- Cut 8/10, Gloss 5/10
- Suggested for soft/sticky and dried-out clear coats (e.g., Japanese/Tesla/GM Denali black and classic cars).
- Rated for up to 1500 grit (wool). Customers also mentioned excellent results on "spider-cut pads"
Medium Cut Polishes
Menzerna Medium Cut Polishes are for signs of use and moderate scratches. Fine abrasive polishes for scratch-free car paints with exceptional gloss.
-
One-Step Polish 3 in 1 - Cut, Gloss, & Wax: our top recommendation for DYI users on passenger cars, this diminishing medium cut polish levels out minor scratches, produces excellent gloss even on dark colours, and tops with a wax to seal the surface. Effectively it goes from a Medium Cut to a Finished and sealed surface!
- Rated for up to 3000 grit sanding marks.
- Cut 5/10, Gloss 9/10
- Suggested for soft/sticky and dried-out clear coats (e.g., Japanese/Tesla/GM Denali black and classic cars).
- Rated for up to 3000 grit sanding marks.
-
Medium Cut Polish 2000 (formerly Intensive Polish 2000): Menzerna's standard medium cut polish does not utilize diminishing abrasives, instead producing a sustained lighter cut. Produces less gloss than the Alternative Medium Cuts but popular with body shops.
- Rated for up to 3000 grit sanding marks.
-
Cut 5/10, Gloss 6/10
-
Cut 5/10, Gloss 6/10
- Rated for up to 3000 grit sanding marks.
-
Liquid+ Medium Cut Polish 2400 (formerly Super Intensive Polish 1500): Menzerna's alternative medium cut polish for soft/sticky and dried out (older) coatings. Well suited to some Asian (Japanese, South Korean, etc.) models, GMC Denali Black paint, or classic cars.
- While less popular than MCP 2500, ultimately it trades a slightly faster cut for a smoother buffing action and higher resulting gloss. In our opinion, can finish out well on all but perhaps the darkest colours (our rule of thumb is 9/10+ gloss for black paint).
- Honestly, most customers I mention it to haven't tried anything but 3 in 1 and MCP 2500 and are suitably impressed by how well this polish handles its niche.
- Like all the Medium Cut Polishes, rated for up to 3000 grit sanding marks.
- Cut 5/10, Gloss 8/10
- While less popular than MCP 2500, ultimately it trades a slightly faster cut for a smoother buffing action and higher resulting gloss. In our opinion, can finish out well on all but perhaps the darkest colours (our rule of thumb is 9/10+ gloss for black paint).
-
Medium Cut Polish 2500 (formerly Power Finish 2500): one of our most popular products, Menzerna's classic "alternative" polish is the mainstay Medium Cut in their lineup. Cuts out deeper scratches than you expect, finishes quite well. In the past, it's been frequently used as a follow up (and even finish!) following an aggressive cut with Heavy Cut 400.
- Rated for up to 3000 grit sanding marks.
- Cut 5/10, Gloss 7/10
- Rated for up to 3000 grit sanding marks.
Finishing Polishes
Menzerna finishes are the perfect car polishes for slight scratches and smears. Absolutely hologram-free finish with an exclusive shine, even on black cars.
-
Final Finish 3000: Menzerna's standard swirl remover produces only a light cut and high gloss; it's most popular in autobody applications. Can be used as a final step after SHCC 300 or HCC 400 on a foam pad, allowing you to skip a Medium Cut Polish in some applications.
- Cut: 3/10, Gloss 9/10
- Super Finish 3500 (formerly SF4000): is Menzerna's alternative, extra high gloss finishing polish. Produces a similar cut to FF 3000 but more gloss, particularly on soft or dark paints that can show holograms. Can be used as a final step after SHCC 300 or HCC 400 on a foam pad, allowing you to skip a Medium Cut Polish in some applications.
-
Super Finish Plus 3800 (formerly Ultimate Finish 5000): Menzerna's ultimate "show car finish" - slightly less cut means it less reliably pulls out diminishing heavy cuts in a single pass, but produces an unmatched glossy wet look. Recommended for older/sensitive paints, and another great choice for soft paints.
- Cut 2/10, Gloss 10+/10
Product Combinations
While ultimately, product combinations will depend on the type and condition of the coating system you are working on, there are some mainstay suggestions well-established in the detailing community.
Obvious combinations are:
- HCC 1000 --> MCP 2000 --> FF 3000
- HCC 1100 --> MCP 2400 / MCP 2500 --> SF 3500 / SFP3800
Other possible combinations include:
- 3 in 1 (and done)
- CFP (and done) or CFP --> SF 3500 / SFP 3800
- SHCC 300 / HCC 400 --> FF 3000 / SF 3500 / SFP 3800
Detailers swear by:
- HCC 400 --> MCP 2500 (and done)
- HCC 400 + 3 in 1 (on the pad at the same time)!
Etc... find what works for you and your situation!
Pad Choice
One last thing I like to note is that (like with metal polishing compounds) pad choice can have a significant effect on the efficiency of your overall process. Let me explain....
Compound Potential
Each compound has a potential for cutting power and resulting finish - by using that compound on an "equivalent" pad, you get some degree of both of those maximum possibilities (e.g., if Heavy Cut 400 has a Cut of 8/10 and gloss of 8/10, you might achieve 80% of that cut and resulting gloss by doing a single pass with a coarse/heavy cut foam pad like the Lake Country CCS HDO Blue Foam Polishing Pad).
Using a Less Aggressive Pad with a More Aggressive Polish
One thing Menzerna suggests for some applications (and to save money on buying multiple compounds) is to take your compound and use it again on a less aggressive pad (e.g., if you used Heavy Cut 400 again on the same panel with a fine/soft cut foam pad (e.g., Lake Country CCS HDO Black Foam Polishing Pad), you might limit it's cutting power to 3/10 but achieve that higher gloss of 8/10).
Using a More Aggressive Pad for your First Step
The flip-side of that compromise is when you use a more aggressive pad to achieve a higher cut - e.g., by using Heavy Cut 400 on a wool pad, you can efficiently knock down up to 1500 grit sanding marks instead of just 2000 grit sanding marks when using a foam pad. Depending on your pad choice, this may limit the finishing capability of the compound to a 5/10 or 6/10. In some cases, this can mean the surface requiring an extra process step (e.g., a one-step polish becomes two steps, or a two-step polish becomes three - I often find that especially dark colours already require a step beyond others!). This is because although you've removed more deep scratches, your second step may no longer have enough cut to level out the aggressive buffing marks you've put into the paint (much like using a sisal fiber buffing wheel to enhance your cut on stainless steel).
In what situation would you want to add steps to your process? Doesn't that defeat the purpose of a diminishing abrasive polish?
Yes and no...
Diminishing Abrasives Self-Refine and Often Make Finishing Faster/Easier than Traditional Compounds
One potential downside of diminishing abrasives is that they are designed to break down and refine themselves quickly - on especially damaged surfaces this can mean that they don't do quite enough cutting during one round of polishing, so you need to apply fresh compound and make a second pass. Traditional compounds help avoid this by allowing you to cut for a longer period; they, however, do not do as good a job of self-refining - particularly if you are using a very aggressive pad - and they may need even more steps to tone down aggressive buffing marks prior to finishing.
Aggressive Pads/Compounds Can Reduce Overall Polishing Time
Another reason to make use of more aggressive pads is to make your overall polishing time shorter (and therefore, less risky). If you were trying to be on the safe side, you could simply attack the surface with a less aggressive compound multiple times to achieve the same correction of a single pass with a more aggressive compound and/or more aggressive pad - the downside is that this introduces more heat to the paint, which can be damaging. It also takes - you guessed it - a lot more time.
A great example of a more aggressive pad saving the day comes from my own anecdotal experience: I had a helper assisting me using a twisted wool (very aggressive) pad with Super Heavy Cut 300 on a heavy truck. I'd done some test areas and determined we could proceed from there to the Medium Cut Polish 2400 on a Lake Country Orange CCS HDO foam pad, and finally Super Finish 3500 on the same pad. I got called away to do some urgent office/warehouse work, and asked them to continue cutting down the paint on this truck - but cautioned them to a) regularly wash or open a new pad regularly, and b) to do their cut on edge (for a more aggressive cut) but to level things out on the flat before moving on. Unfortunately upon my return I found that they had followed neither piece of advice (they no longer work here). Not wanting to go over the entire truck again, I proceeded with the Medium Cut Polish... and found that I needed not one, but five passes to knock down the initial rotary buffer marks. Yikes!
Fortunately, we have access to a range of specialized pads so I opened up a Lake Country HDO Heavy Cut Microfiber Pad, and hit the surface with the same Medium Cut Polish... voila! A single pass! The true test was finishing... but luckily, I was able to pull my second step as planned with a single pass of the Finish polish. Ultimately, the use of a more aggressive pad saved me buffing over the paint many times over!
In Sum
At the end of the day, your budget, experience, available time, and - most importantly, the paint itself - dictate the best options for you.
One-Step Options
Cut Force Pro and One-Step Polish 3 in 1 both make excellent choices for one-step polishes, even on dark colours (in the right conditions). For lighter colours or slightly marred paint, consider a single process step polish like MCP 2400, MCP 2500, or SF 3500.
One-Two Combos
Provided your initial pad choice isn't too aggressive, Super Heavy Cut 300, Heavy Cut 400, and Cut Force Pro can all be combined with a finishing polish like FF 3000, SF 3500, or SFP 3800. Menzerna also suggests using Cut Force Pro, Heavy Cut 400, and One-Step Polish 3 in 1 as their own second step by using them again on a softer pad. You can achieve a comparable finish and don't need as many compounds to do so!
Three Step Processes
Obviously, you can utilize more traditional means where practical: a single-step Heavy Cut, Medium Cut, and Finish polish make for a thoroughly perfected surface.
In some cases it can make sense to add an in-between step even when using a diminishing abrasive, such as when you use Super Heavy Cut 300 on a very aggressive pad and need to tone it down (either with SHCC 300 again on a less aggressive pad, or a dedicated Medium Cut) prior to finishing.
