I recently purchased a '71 Road Runner from the original owner in Chicago. The car is covered liberally with Ziebart, a product widely used in northern states and Canada to prevent rust. My car has it everywhere and I would like to remove it in some places. Does anyone have a suggestion on how to remove this stuff. I visited with Ziebart staff people and they didn't have a suggestion. I've tried your regular solvents, etc, with no luck. I'd appreciate any ideas.
