Reviving a 16 yo thread. Figured there should be better ways out there. Removing the decals on my 1998 Sylvan. Got one side done yesterday. To remove the glue, acetone did nothing , mineral spirits did nothing. Gasoline did the best but a lot of rubbing. Haven’t tried anything else yet. The 3M stuff seems pricey. What have you used with good results?
Also learned a secret. Pin stripe manufacturers put tear point every foot so that no matter how much heat, pull power, angle of pull, speed of pull, or any other factor you apply you will never remove more than a foot of pinstripe before it rips!
