Darrell Cook 1st told me about this oven cleaner method of stripper for plastic when I wanted to remove clear coat from a radiator fan shroud. It does work! Recently, I wanted to remove interior dye from a door panel and I used oven cleaner.
Dave, thanks for the "heads up" on the Deco-Premium paint pen. I went out and got one myself. I went crazy on dash carriers during a recent stormy day.
