1) Use the filler on bare scuffed metal to give it something to bite into. If you put filler on too slick of a surface it won't hold. When it's leveled use primer (at least enough to be able to get the sanding scratches out). If there are any imperfections left like pinholes from the filler use putty to fill those. Then surfacer.FORDification wrote:Oh yeah....had a couple more questions I forgot to ask:
1) The recommendations here have been to apply the epoxy primer, then filler, then primer/surfacer. It seems most of the other bodywork forums I've visited suggest the order as epoxy primer, then primer/surfacer, then filler. Does it really matter on the order?
2) What about seam filler? If I'm going to use the factory-type seam filler in places where it was used by the factory, when should this be applied?
2) Seam sealer should be used after primer, and it needs to be completely dry before anything is sprayed on it. As it dries it shrinks and will cause paint to crack.
