if you need to get paint off of anything, windows, lights, etc., use this stuff found at napa for like 3 dollars called brake clean (we use it at the shop). only the green bottle though, the red one does nothing. you can clean anything with this stuff (engine, window paint, and tail pipes) but don't use on paint. it will strip it off your car! as noted that it will take it off your headlights, tail lights and windows...
