sorry for the long post
well, its not just paint. I sanded everything , i used one of those foam sanding block things dont use anything coarser than like 400 or you will make your painting harder. All you want to do is scuff it and get that top layer of grime off. Then i wiped every thing down with 91% rubbing alcohol. give it like 5 mins to dry/ evaporate. Then spray 2-3 coats of the adhesion promoter on. The stuff will look like its evaporating but its on there, just spray it on and wait 5 mins before you do the color coat. then spray like 10 thin coats of color. If its not black the first pass thats ok, you just want the paint to be sticky. It will fill in and look right as you get more passes done, 5 mins between coats is good, dont wait more than 15 mins though. then add a few coats of clear and your set. let it dry overnight and sometime the next afternoon you should be ok.
I painted my stuff on the truck, so get yourself enough plastic drop cloths (the thin cheap ones work great and are like 1$ each) to cover the entire truck. it took me 3 9x12 cloths to cover the truck ab and a whole roll of 3 inch blue painters tape.
another thing i did is to tape the edge off before messing with the drop cloth then tape the plastic to your taped edge. The idea here is so once everything is dry you can remove the plastic separately from your taped edge. Now take a sharp pocket knife or a razor blade and cut a line where the tape meets the plastic. The point of that is the paint you just sprayed does not care about your line, and when you pull that tape off you may peel paint with it if your not careful.
