Don’t know of anything that will stand up to brake fluid if that is what you are wanting. It is just some nasty stuff. Thinking of trying powder coat on mine when I have to do a rebuild, but don’t know if even that will last very long.
Dam break fluid eats away at paint & powder coating eventually. Maybe epoxy paint would hold up best. I did a dot 5 experiment on my rear brakes. Flushed the system with alcohol then plenty of Dot 5. It's been 4 years now, and no issues. So the clutch and front brakes will get the same treatment when I change master cylinders.
