Tar-like undercoating on 63 Valiant...any way to remove it?
I sprayed that Goo Gone Automotive Gel on frame rail, let it sit 4 hours or so, sprayed it again, then used metal putty knife. About 5 minutes of scraping and it broke free and left surface looking pretty good. Mine is a factory undercoated car but I think I spray bombed some more under coating over top of it back in the '80s to hide that fiberglass patch in the floor (full floor replacement soon).
Mine is an original Formula S car so I can't use Needle Scaler cause it might leave dimples :thumbsup:
