If the panel is abraded properly, Epoxy primer would be a better choice over POR products, as the epoxy is far better at preventing rust creep than any other paint substrate. POR type paints (moisture cured urethane) were originally formulated as a paint for bridges, and there (as well as on vehicles) the MCU's are far from a permanent rust solution and don't match up to the sales hype.

This makes perfect sense, thanks. Another point is POR15 doesn't adhere as well to perfectly clean metal as far as the patch is concerned. A 2K epoxy primer would be ideal. In my mind, I was assuming he would be brushing on POR15 in area's with surface rust in the hard to reach area's anyway. If only there was a 2K epoxy primer with built in rust encapsulator and while were dreaming....in a rattle can....
