Please can somebody who knows, shed some light on this. I’ve recently bought some metallic basecoat, from my local auto paint supplier. The data sheet says to sand between P360 to P600 for substrate preparation. Looking around on here, I believe it is more usual to sand a bit finer to 800 grit for metallics. What would be the reason for a more coarse prep? Thanks.
