I removed a leather wrap from my wheel. Underneath there was something like a continuous double-sided white tape. Most of this was peelable, but some was not. After removing this there's a very tough closely adhered layer of transparent glue. This seems almost impossible to get off. Acetone does nothing. I'm now painting on Goof Off adhesive remover. I'm trying to scrape off with a plastic spatula. It's really barely working and will take many many hours of work with the possibility, I think, of scraping the chrome finish. What solvent should I be using?
