Best Way To Remove Paint From Rubber????

Maybe TSP, which is in any hardware's paint section. It usually doesn't attack plastic, which is what most rubber is. It will corrode metal and etch glass, so be careful. Another idea is Super Clean, at Walmart. I have used it to remove paint/chrome from the plastic dash trim. Many model builders use it. You need to let is soak 1-2 days, so wet rags with it and wrap with plastic film so it doesn't dry. I did find that it attacks aluminum quickly when I held down some parts with an aluminum piece.
