I have a friend who has painted for somewhere around 30 years and he is always telling me that I am doing things wrong and tries to convince me to do it his way, I told him my information comes from this forum only and he said you can not believe what they tell you. I am getting ready to repair a heavy scratched front plastic bumper cover on a subaru forester, My friend said to use evercoat rage to fill lows then 2 k primer and paint. I told him that I follow what you guys tell me and that is it, I said that I use SEM plastic bumper repair to fill over epoxy primer then 2k and go from there. He said I must have fell on my head when I was a baby! I would much appreciate one of you guys to verify that my process is the way to go and should the Rage be used on plastic bumpers?
