Anyone have any sucess at removing old paint base/clear (urethane clear ) from front bumper fillers. I’d like to strip them before going back with new paint. The bumper got into them and cracked some of the paint so I resprayed them. Now with 2 layers they’re cracking. I need to get back to eurthane before going back with new paint. DeKote will soften the paint but there’s still a lot of scraping to get it off.
