POR15, undercoat, or sprayon bedliner?

After asking 67Dart440GT more specifically about what he did, I think I'm going to to with the epoxy primer on the rest of what I have to do as well, rather than just the straight product on top of metal. With the Eastwood product on top of that (on areas that will be hidden anyway).

This is a good thread, lots of good ideas & thoughts here.

Oh yea, interesting, so the epoxy is the bonding agent to the metal, then the eastwood over that for heavy durability.. there must be a time window to apply eastwood over epoxy primer for proper chemical adhesion if that is even possible.. hmm, I believe por15 says not to put their product over other products.
