Grit Level vs. Application Product?

[imported_ByrdDogX]

Is there a guide or chart somewhere that you guys know of that indicates what a product can do based on grit sand scratch level?



I was reading about the Optimum Compound and saw this sentence that indicated it was able to remove 1200 grit scratches.



"Optimum Compound removes deep swirls, scratches, and oxidation like a traditional compound. It can remove 1200 grit sand scratch marks while still performing like a polish."



So is there a guide that can tell me what a product can removed based on grit level? I hope this make sense because the more I type the more confused I get!

It’s not possible. There are too many variables involved.



Different abrasive sheets from different suppliers can leave scratch patterns that are completely different to buff out, even if they have the same grit number. The very same piece of abrasive will leave a different scratch pattern when used by hand, by DA or by DA’s with different speeds or orbits. The very same piece of abrasive will leave a different scratch pattern when used by bare hand, rubber sanding block or foam sanding block, not to mention when used dry or wet, with plain water or with a lubricant.



As many variables as there are in abrasives, there are even more in paints. The variations in paints cause huge changes in both the scratches from sandpapers and the workability with the compounds.



The numbers thrown about by manufacturers are only rough estimates. It’s up to the end user to dial in a process that works for them on any given finish.
