I have quite a few replacement panels, but the rest of the car will be bare metal. Thats why I was going to use the self-etching primer. After Freethinker52 told me about the epoxy, I went on the hunt for info via Google and found that the epoxy was the new way to cover bare metal and self etching was old school.
I've read a lot about Barry and his SPI products and everyone seams to like them. I will have to log onto his website and check it out.
