Can I use epoxy primer over the primer on new panels or should they be sanded to bare metal and primed with etching primer ?
Why in the world would you want to "80 grit it"? If you strip it, you should be able to use 180 grit at the coursest, to get good adhesion, although I don't feel that it needs to be striped, unless there is damage to the e-coat. 80 Grit would be fine if you need to use it to strip.red65mustang said:Rule #1: assume nothing, buyer beware
Rule #2: do the research, get the facts on your panels
The coating on your panels:
"maybe" laquer based transport primer on slick steel, needs to come off,
"maybe" crummy thin cheap e-coat on slick steel
"maybe" correctly applied e-coat,
I've never found "good" e-coat on any Mustang imported panels.
Strip it, 80 grit it, epoxy it, atleast any areas that get abuse from stone chips, moisture, etc.
