Yesterday, I went to Wal-mart to just look around and shop for my new tennis shoes, and then i remembered my messed up spray paint car body. so I asked the guy and he said that "KleanStrip Laquer Stripper"works, so I bought it and checked it out.
when I dripped a little bit on to a section, all of a sudden, flakes of paint started to come off, and when I washed it, I was clean!
I also used it to clean my airbrush.
I put it in a little pipette and then squirted it thoruogh, and all the dried and caked up paint shot out.
It's good stuff, and you can buy it for $5
hope this helps
