I have been using Tumbler silicone and grease remover. I spray it on about a 4 foot square section at a time, wipe it off and blow off any remaining moisture with my air hose. I do this before sanding down a panel, and after sanding the primer. I used the same stuff on my last paint job too and it turned out fine. I did two things different on this paint job. I used the evercoat metal glaze instead of my usual filler, and it was my first time using Dupont paint. I asked when I bought the paint if I needed to spray on a sealer first and they said I didnt need to. Would that have made a difference, or is it some other problem? Other than that, the paint looks good, shiny like a mirror.
