A good epoxy primer is the way to go over clean sandblasted metal in my opinion. It will eliminate the etch coat process and give you excellent long term protection of the surface. This is important if you plan on leaving the metal in primer over an extended period of time. We have used this method many times over the years in the shop where I am employed on the restorations we do and have never had a problem with it. The epoxy will not only provide protection but it will also give you high film build to help level the sandblasted panels. Etch will give protection but will have to be primered anyway thus making it at least a two step process to get the results you want.
