I've used the Eastwood Brake Gray on my 55 Chevy with Dot 3. Yes the whole system was cleaned out prior. I had to put all new brakes on it ofcourse. But anyway, the master cylinder was painted with Brake Gray and it seems to be holding up well. Just make sure you allow it to dry for a day or so. If you don't, any fluid on it will wipe the paint right off. I didn't wait too long and spilled some and where it spilled rusted, but everywhere else is like the day I painted it. The car isn't in a garage either.

Another great tip is to heat the part with a small propane torch. Most people forget that there is a ton of moisture in the air, no matter what temp. Lightly heat a bare steel part and watch it get sweaty. Once it stops, paint the part. It also helps draw the paint into the pores of the part. If you've every been in a spray booth, that's why the heat the booth up with your car/part in it. Gets the moisture out. If not, the moisture is locked in.
