I've sprayed my frame and all my chassis parts with an etching primer as well as a 2k Urethane high fill primer and there are some fine lines I would like to fill. Do I have to sand it all off and then fill or can I just scuff it where I want it filled and spread some Evercoat Gold on there. I'll then sand and spray sealer over top before the color coat.

Any ideas, if I have to sand it and start over I'll probably just leave it cause I'll probably be the only one to notice. I tried to put another shot of the primer but that's three coats and they're not filling in.
