It will work as a mild stripper but you need to let it sit for a long time. Paint strippers are a better product if you are going to strip an entire car. Personally I like Captian Lee's Spra-Strip paint stripper. Good for metal and fiberglass.

There are better, more efficient chemical paint strippers out there if that's what you are looking to do. Save the brake fluid for your brakes.

there is no need to remove ALL the old paint for a respray , good prep and a sealant will take care of it

. . . . would you use paint stripper for brake fluid . . . or to thin laquer?

Ok, so I have heard all sorts of things regarding brake fluid. Some say it softens the paint and you can just wipe it off. Other people say that it will corrode the metal. It runs through still lines though. It might corrode aluminum. Has anyone ever used it to clear old paint off and prepare the car for a new paint job? If it works, it sure beats sanding. Does it affect the coating of new paint being applied, or would you need to flush it off with lacuer thinner first?
