When sanding a car, start with a coarse grit sandpaper, typically around 80 to 120 grit, for initial paint removal or to smooth out rough surfaces. For subsequent sanding, use medium grit sandpaper, like 320 to 400 grit, to refine the surface before priming or painting. Finally, finish with a fine grit, such as 600 to 800 grit, for a smooth surface prior to applying the final coats. Always ensure to use wet sanding techniques for the finer grits to minimize dust and achieve a better finish.
