As a consequence of running TaG 100cc, I’m having to remove some heavy “rub” marks off my bodywork after each race. I tried the WD-40 and steel wool, scraping with a razor etc but too tedious and time consuming and really didn’t turn out well.
Since I’m retired, I have some time to experiment. What I found worked the best was steel wool sprayed with non-chlorinated parts cleaner (MOC Parts Wash). It seems that the Parts Wash softened the rubber and I was able to get almost all of it off. As a disclaimer, I’ve only tried it on my body work decal which looks like shiny aluminum, so if you try it, please try it on a small area first and have it well ventilated and use gloves. Please try at your risk.
Are there better ways to remove rub marks?
