I did a search but didn't see this discussed or I missed it. When doing body work, what is the order of repairs after welding? Is it better to use body filler on bare metal or primer?
Also, for repair patches that won't be painted for a while, what's the best way of protecting it from rust? For now, I've been using a spray can primer just to get something on bare metal, but I already see some rusting in the seams so maybe I wasn't putting a thick enough coat on. An epoxy primer is probably better, but not always feasible when doing small areas. These are areas that may sit around for months or even a year before I'm ready to paint. Can anyone recommend a good spray can primer, some thing I can use for spot repairs?
