Two owners ago, my '88 Notchback got a "home" paint job. The painter painted most of the window weather stripping a nice glossy single-stage black. Now, the weather stripping is in good shape other than the paint cracking on it.

I know that DOT3 Brake Fluid will eat rubber, right? But what about DOT4? I've heard it will only eat paint but is safe for rubber. Anyone know? Would this be safe to try?

Any other suggestions on getting lots of hard paint off of weather stripping?

 

I'm pretty sure Dot4 will eat rubber too.

I wouldn't mess around with using brake fluid to remove the paint. When there are so many chemicals designed to remove paint.

Have you tried taking a razor blade and scraping it accorss the paint? The rubber will flex, causing the paint to flake off.

 

Vasaline will brake down some enamels, but it will also effect rubber some. If its the window sweeps I would just replace them because the residue from the stripper would probably transefer to the glass everytime you roll them down and up.

 

I use laquer thinner to clean my rubber parts.

It'll remove paint, oil and dirt, just wet your rag or steel wool (if the paint overspray is thick) and scrub.

When I was restoring my Corvette and S10 Blazer this method saved me a lot of $$$ on rubber hoses and weatherstripping that was otherwise in good shape.
