The Mothers stuff ruined mine. I didn't keep up with it and left them go for to long and now the black plastic trim on the outside of my jeep is a gray, chalky looking mess. I started using the 303 stuff and afterwards, it looks like new again, but if I go to long without reapplying it, it turns gray again. My tj I had before never had any problems with the trim turning gray, probably because I might have washed it 2, 3 times at the most, and I don't think I ever put anything on the trim. I've taken better care of this one, or so I thought and now the trim looks like hell.
