Used 100% Acetone, and it easily took off the spray paint. Still got the tight spots to get, but I can see the original paint. Gotta love that sea foam. It is a Scott bike, it appears to have the same decals as the yellow one pictured above, but they were removed by who ever spray painted it. The Acetone defiantly left a dull finish so I will wet sand, then try buffing it with some compounds and polish it to try and get the paint looking good again.
