I've sprayed three coats of K36 primer/surfacer and blocked sanded with 180. Everything looks and feels pretty good. I ewent down to epoxy primer in a few places and t ometal in a few small places as well. see picture. alsothuogh this isn't my car, it looks just like the phase I'm in.
My question is, do I respray the whole car again with 2-3 coats of primer /surfacer before I block sand with 400 and 600 or do I just spot coat where I broke thrugh the surfacer ??
