Are you feeling lucky?

If it's the factory-original finish with the linear polyurethane 2-part clear coat, it should be extremely resistant to pretty strong solvents, even including acetone, such as lacquer thinner or non-chlorinated brake parts cleaner.

Using anything with acetone would take the old crusty adhesive off in a hurry.

If you have a cheap respray, however, you'll quickly damage your finish and have color transfer onto the towel you within seconds of applying an acetone-laden solvent. This would be very bad. A milder solvents either won't work at all, will require extended dwell time, and/or mechanical agitation (which is another issue if there is dirt in the old adhesive, as it can get scoured into the paint and cause many scratches). There are a few different products out there often recommended for things like removing tar from paint, which could work ok.

Hope that helps, and best of luck.
