View Full Version : Grading your Grit depth?

I see may polishes and paint correction products give a range i.e. 1500-2500 grit or 3000 grit. How do you judge how deep you need to go? I don't want to use something for 1500 grit, when I really just need a lighter product. It would seem that you're doing more damage to the paint (using a stronger product) that you need to.

These grit ranges refer to the wet-sanding marks that the particular polish will remove. For instance, V32 Extreme Compound is rated to remove up to 1200 grit sanding marks, while the lighter polish V36 will only remove up to 2000 grit sanding marks.

We always recommend you start polishing with a test spot. Start with a medium-aggressive pad/compound combination like V36 on an orange Hex-Logic pad in an inconspicuous spot, and gauge the effectiveness. If you need more cut, go up to a harder compound or pad and try again. Once you find the right combination to get the desired results, repeat around the whole car.
