Aircraft stripper
I powdercoated a pulley set and screwed it up (bubbled in the grooves!) I soaked the entire pulleys in a pan of aircraft stripper and all the powdercoating wouldnt come off, I know a guy with a industrial sand blaster and finally took them to him, he finally got it off and even then there was a couple places where it was still on!!! Good luck your gonna need it!!! :mrgreen:
