What should a sanded surface look like between coats? I am using an oil based paint on some flush panel doors.
I am using a Wagner spray gun. I have already applied my first coat.
I intend on using a 240 grit sand paper after the first coat and and finishing with 320 grit sand paper in prep for my last coat.
When I look across the surface should it look completely flat or should I see little stipples / bumps?
