Well before I joined, I have been searching final grits before I go on to the next step. Not being a professional or very experienced I would like to work up a cheat sheet because I tend to forget things overtime.
I ask what the coarsest grits would be acceptable for a quality restoration? I know not everyone has the same opinion and some may use finer grits for various reasons such as so they don't inadvertently break through sanding. So please I'd like to hear from as many of you as possible. Here is a draft of my cheat sheet.
Bare steel for epoxy P80
Epoxy for filler or poly primer: 7-14 days Scuff or sand 180-320.
Past 14 Days - Scuff or sand 180-320 & recoat with epoxy.
Epoxy for 2K primer: 8 to 14 days Scuff or sand 180-320, 180 preferred.
2K primer for additional coats of 2k: 180, maximum of 24 hours prior to next coat of 2K.
2K primer or poly primer for un-reduced epoxy: 180?
2K primer or poly primer for epoxy as sealer reduced 1:1:1 for solid color Base or Single Stage P320?
Reduced Epoxy as sealer for Base or Single Stage: 8 to 48 hours not sanded before color?
If sanded 400-wet for solid colors, 600-wet for metallics?
