final coat - ETEX, SYSTEM3, DEVCON two part epoxies
water based poly's- you can add clearwaterbased to any of your waterbased "painting coats" and then a final coat of clear to seal everything up and provide a surface to "scratch" to provide the final epoxy better adhesion without damaging your paint job
any of the polyurethanes will do the trick for the "scrach coat" that DAD mentioned or you can spray the envirotex as he does...it's simply a way to seal you work and creat a surface that will accept the finish epoxy and provide a good bond
