What paint for my brake perch?

It's time to rebuild my front brake master cylinder. A small leak caused all the paint on the perch to bubble and peel over winter.

I've got my rebuild kit (and some snazzy new braided steel lines) and am ready for the rebuild.

But I need to put a fresh coat of paint on the perch too. Will any old black paint due or is there something that will stand up better to the brake fluid if I happen to drip it on the perch when topping off my fluids?

I've got 3-4 partial rattle cans of black, including some high-temp stuff. Will that be any better for this job?

VHT satin black caliper paint is durable, but no paint will stay on if brake fluid leaks on to it. If painted parts are waxed, quickly wiped up spills will not eat paint. Best thing to do is use a high dollar silicone brake fluid, then you can use any paint without worries.

Be careful if you decide to use DOT-5 silicone brake fluid; it does not play nice with any residual DOT3 / DOT4 brake fluid lurking in the brake system, and it should be changed on a regular basis to avoid problems with moisture "puddling". Ed

Someone here on KZR suggested Gun Koat for fuel resistance & said it also resists brake fluid,
but he was a one-post wonder. Assuming he meant Gun-Kote, it comes in several colors.
Here's the quote:

KG coatings - Gun Koat, impervious to any solvent, even brake fluid. Most paint that isn't heat cured takes a while to cure. some take months to fully cure. I have used a product called "lip seal" to seal the seam where paint meets bare metal at the filler. I believe is is a isophthalic epoxy, which is what the caswell tank liner is as well.

Gun-Kote is a good idea. It does wear off after heavy use though. Any ceramic based paint should work. FR primer is impervious to Skydrol(extremely corrosive hydraulic fluid used in aircraft/rocket control systems) resistance. Its the ugly green we used to paint on all the aluminum on aircraft and rockets. Powder coat is impervious as well.
