400 grit at a minimum, I would say 500 or 600 for your final sanding would be great. SEM Self Etch works good, but doesn't fill very well. We use it on small sand through areas here in the shop, and have for many years.Question for @Jetpainter ....or anyone with some good fiberglass painting experience. I will be using SEM self-etching primer over the fiberglass, then auto base-coat/clear coat paint. I've been finishing up the bodywork stuff by wet sanding with 320 grit. Should I go finer than 320? It feels and looks butter smooth at this point, but not sure here? If I go finer it starts to get a sheen, so it seems like I'd be loosing some "tooth"?
Thoughts???
