This document provides sanding instructions and recommendations for different stages of repair work including removing old paint, prepping filler material, sanding primer, and final paint blending and finishing. It lists the recommended grit sizes, tools, and pads to use at each stage to achieve a smooth surface and properly blend in repairs. The goal is to remove defects and imperfections and enlarge the sanded area at each progressive grit level in preparation for the next steps of applying filler, primer or paint.
