Although I am still such a know-nothing rookie, when I started my 79 camaro project, I knew even less.....like NOTHING. So, I was talked into spraying Dupont Corlar epoxy (which now I know is not really for automotive applications). I had the body shell to bare metal, and sprayed two coats of that stuff. That was almost 18 months ago, and the Dupont has held up great, but I really want to start again, but really don't want to go back to bare metal unless I have to. I still have some minor filler work to do, and found that due to my inexperience, I really sprayed the Dupont epoxy rather thin on some spots.
I want to spray SPI epoxy (2 coats?) and more or less "start over". Question is: Is if safe to spray SPI epoxy over this stuff? If so, what should I use to scuff it up so that the SPI will have a good foundation?
Second question: How far do I sand the urethane bumper covers, and do I use epoxy primer, 2K, and base coat? The back bumper cover is mostly original paint (as far as I know), the front is an Ebay piece that has a couple of small places that need to be fixed (gouges but no holes or tears), what product can I use to fix those spots? It seems to have epoxy primer over it now, but I have no idea how many coats of whatever might be under that. Would I make it smooth (nicks, scratches, etc) and then spray it with epoxy/2K/base or just epoxy/base? Or should I use this:

If this is the primer I should use, does it replace epoxy and 2K, or just epoxy, or do I still spray epoxy and/or 2K over it?
Any help would REALLY be appreciated!
