Best epoxy primer

The reason for epoxy primer is the corrosion resistance factor. I also will be doing a lot of rust repair and the initial blast and prime will cover all the good sheet metal and the rest will be in stages as I replace the rusted metal. The car may be in and out of the garage a few times during this phase. Then a quick sand to rough up the epoxy and a coat of high build sand able primer to start the body work.

I will be using a devilibiss flg4 finishline hvlp gun ( if not, I have some of my old school guns; a sharp #75 and a binks #18, both guns spray well).
