Hey Dave,
I inquired on the tech line of Southern Polyurethane about their epoxy primer. He said the self-etching primer should come off before applying epoxy. It may be fine in the short run but he couldn't speak to how long it may last but leaving it and shooting the epoxy over it.

I have a small compressor but would certainly need a low-volume spray guy to minimize overspray, etc, giving my garage situation. Doesn't epoxy require a special respirator as well?

How's it going with your hood sides, etc? Are you shooting paint yet?

Can you believe this thing is now over 1900 views???
