Polishing and Paint Correction
The Best Compound for Single Stage Paint in 2026
On single stage there is no clear coat to sacrifice: you are cutting the color itself. Only some makers will say whether their compound belongs there, and one says it does not.

What to look for when there is no clear coat
Single-stage paint is color and binder in one layer, with no clear coat over it. Cut into it and you are removing pigment, which is why the pad comes away the color of the car. Old single stage is usually oxidized on the surface too, so it needs cutting and it punishes cutting, at the same time.
Three published things narrow the field. The stated paint types, because makers who have tested on single stage tend to say so and the ones who have not stay silent. A cut rating, expressed as the sanding grit the compound removes, because on a finite layer of color you want the least cut that works. A published method, because pass count and pad choice are how you control how much you take off. Nothing here publishes a figure for how much material it removes, and nothing on this page is presented as safe by default.
What each maker states about paint type
| Compound | Price | Stated paint types | Cut rating | Published method |
|---|---|---|---|---|
| McKee's 37 BEAST | $24.99 (8 oz) | All, including clear coat and single stage | 1,000 grit or finer | 5-6 overlapping passes |
| Adam's One Step Polish | $22.99 (12 oz) | Clear coat, single stage, lacquer, gel coat | Removes 2000-grit sanding scratches | 4 drops, white pad, speed 3-4 |
| Koch-Chemie Heavy Cut H9.02 | $27.99 (250ml) | All, including soft and scratch-resistant | Sanding marks up to 1,200 grit | Not published |
| Optimum Hyper Compound | $26.99 (17 oz) | Not published | Removes 1,000 grit and deeper | Not published |
| Shine Supply Chop Top | $26.00 (8 oz) | Hardest clear coats; not single stage | Up to 1500-grit sand scratches | Rotary and wool; DA with microfiber |
The one that says it in writing
McKee’s 37 state BEAST is safe on single stage as well as clear coat, and they back it with the two things you need to control the cut: a rating of 1,000 grit or finer, and a method of five to six overlapping passes. They also name the pad options, wool, foam or microfiber, by the cut you want, and claim no dusting.
That combination is why it leads. On single stage the compound is only half the decision and the pad is the other half, so a maker who tells you both is giving you a way to start gentle, check the panel, and step up only if you need to.
The gentler route: start with less cut
Adam’s One Step Polish names four finishes explicitly, clear coat, single stage, lacquer and gel coat, and states it removes 2000-grit sanding scratches. That is meaningfully less cut than the compounds above it, and on thin original paint less cut is usually the right opening bid.
Their published method is unusually specific: four drops on a white foam pad at speed 3 to 4, moving to an orange or blue pad at 4 to 5 when you need more. Start there on a test spot, and only reach for BEAST if the oxidation does not move. The one-step roundup covers that class properly.
The two that do not mention it
Koch-Chemie H9.02 states it suits all paint types including soft and scratch-resistant, cuts sanding marks up to 1,200 grit, is silicone free and dusts minimally. Soft paint is the category most single stage falls into, but Koch-Chemie do not use the term, so it is an inference rather than a claim, and it is ranked accordingly.
Optimum Hyper Compound publishes a clear cut rating, 1,000 grit and deeper, and states it finishes like a polish, which on a car you do not want to compound twice is a real advantage. It publishes nothing about paint types at all. The main compound roundup ranks both without the single-stage constraint.
Protecting it afterwards
Freshly cut single stage is porous and hungry, and it wants protection the same day. The classic-car wax page covers what the wax makers publish, which is less than you would hope, and how many times a car can be polished covers the budget you are spending from.
What to buy
- Single stage, stated by the maker: McKee's 37 BEAST Compound, $24.99.

Every pick, with the working
Each entry lists the specifications the maker publishes, the axis scores those specifications produce, and what you give up. Rows that read “Not published” are not omissions on our side: they are figures the maker will not commit to in writing, and they cost the product points on the transparency axis.

5The hardest clear coats, and nothing else
Shine Supply Chop Top
Shine Supply
Skip this one. Shine Supply say to skip it on single-stage paint, and they state it is for the hardest clear coats. That is the maker ruling their own product out for this job, which is the most reliable kind of evidence on this page.
$26.00 for 8 oz of Shine Supply's highest-cutting compound: zero fillers, VOC compliant, rated to remove up to 1500-grit sand scratches on the hardest clear coats. It was designed for a rotary and a wool pad, and Shine Supply tell you plainly to skip it on single-stage paint.
