Frustrated with inability to do body work!

It looks like you are ready to put a first coat of primer on it now. Be sure to use a good degreaser first.
After primer, guidecoat and either 240 or 400 depending on how close you are to final.
Just before the last coat of primer when you have it as close as you can get it with 400, then use the glaze
to clean up small imperfections.
