I've put 3 coats of primer on and sanded it smooth using 220 grit. I just layed 2 light coats of paint on it, and I now see light scratches, which has to be from when I sanded the primer !!! please tell me there is something i can do without having to sand down to the primer.
220 grit is nowhere near fine enough! I suggest you spend some time with my good buddy the Ultimate Painting and Refinishing Thread!!!
