I will try the lacquer thinner trick to see if these panels are E-coated or not. I'm getting my panels from CJ Pony Parts out of NJ. Thanks for the advice.
almost all reproduction panels are e-coated now unless they come bare (some floor pans) or are pot metal. The panels from CJ will be e-coat. Some people on here don't like the e-coat and take it off. The reality of it is the e-coat is probably stuck on there better than anything you could apply yourself since the panel is dipped and the coating is actually stuck to the metal with electrical attraction. You can read all about the process here if you wish:
I was taught to scuff the surface with a red scotch brite (until the panel is completely dull and has no gloss remaining) and then prime over this. Definitely go epoxy over etching primer. Etching primer's only use is for bare metal anyways, and if you have no bare metal then you are getting no function out of it. Epoxy has superb bonding to bare metal and superior corrosion protection.
If you haven't purchased your paint yet, I'll throw you a tip and highly, highly, highly suggest you looking into SPI's Epoxy (and their 2k primer too). I'm going to guess it costs as much as the Nason does (I don't know what the Nason runs), but not only is it far better than Nason, it's arguably one of the best epoxies on the market, period. And the seven day tech service you get with Barry, the owner, (even after business hours) is a God sent. I'm not trying to advertise for them, but when I find a good product with good service I'm for sure going to tell other people about it.
