Brake cleaner is great for removing adhesive… but it does pull up some paint. I recently used it to remove some decal adhesive from my skeeball machine when I was replacing the decal. The rag had some yellow paint (not much) on it when I was done, a big reason I would be nervous putting it on a playfield. But I have had great sucess with Rustoleum's Adhesive Remover pulling side art adhesive from arcade machines. It works MUCH better than Goo Gone and didn't hurt the paint on the cab at all. It only took about 15-20 minutes to remove all the adhesive from the side of a cab. I'll be pulling the mylar off my Grand Lizard next week and might try the Rustoleum, but was leaning towards the Goo Gone since I had read of so many people using it. The Rustoleum uses the same active ingredient as Goo Gone, but has a different concentration. Anyone here ever try it before?
