I have had similar experiences with urethane paints. Most are somewhat
resistant to brake fluids. They are also more difficult to sand, abrasive
blast, etc. Be sure to wear a good respirator with fresh organic vapor
cartridges or better yet a supplied air respirator when painting with
urethanes. Without a respirator you may become sensitized to the Isocyanates
in the hardener. This may cause a severe athsma like reaction. Once you are
sensitized to it, you will react to it with any exposure. Joe(B)

When I painted my race car, I used PPG's cheap catalyzed acrylic urethane
called Omni AU. I mixed as directed 4-1-1 and the paint sticks pretty
well.
I have spilled Castrol LMA directly on several places on the body (front
left fender, driver's door and in the engine compartment) and the paint
didn't soften or lift. I was very surprised (and somewhat delighted.
I'm not a fan of silicone for a bunch of reasons. But that's like a
religious thing for car guys, and I don't want to start folks ranting on
the topic.
