I'm wet sanding my cab and have a question. I have been sticking to 1500 except for where I have runs. So like on my roof for example only 1500 as no runs and just some trash. The question I have deals with trash in the clear, dirt/dust. I have everything pretty flat but where the trash is I have kind of a ring still. What I have been doing is using some 1500 on a small block on these areas to take care of it. But my question is if there is a better way? It seems like no matter how hard I look for them I miss one. I'll work on a 2x2 area, think it's done and then do a walk around and find a faint one i missed.
