Just sanded and primed my first Old steel case that i had laying around to practice painting before getting to the real thing and i have a few questions...
I sanded the case with 180 grit sandpaper using a flat electric sander for a good 30 minutes or so. There were a lot of "high points" especially near the edges where the original paint was stripped all the way down to the metal.
But no matter what, a lot of other places in the center still had paint on them. Is this normal? and is it ok to proceed?
I then proceeded to give 4 light coats each 15 mins apart with Tremclad Rust Primer. After about 1.5 hours of drying, i started wet sanding the primer layer. While i was sanding, a lot of pieces of paint was coming off, Small rolls of paint which was similar to the types of bits that come off an eraser when you use it a lot. I figured this was normal and continued. During the wet sanding of the Case, there were still a lot of "high points" and the sanding ate all the way down to the metal again. In Crimson sky's book, he says just to sand it some more, and then add some more paint eventually. Will this just occur again when i prime it some more?
Thanks for the help.
