Looking for the best eastwood rattle can for cracks & crevices, hard to get to areas before the epoxy primer is applied. Job has been blasted, metal wash & conditioner, and 1 coat of epoxy, then repairs made over the last year. Some small amount of rust has formed in the hard to get areas where the repairs have been going on and I would like to spray a rattle can in the area. The rust has been taken care of the best we can, just want to get into the tight spots a little better. My question is, what is the best product to use on the raw metal before hitting it with epoxy?
thanks very much,
