Painting a Master Cylinder

POR 15 makes a manifold grey brush on paint. I use it on all my exhaust manifolds, you brush it on and when it gets hot it 'melts' into the cast iron. The best part is that when it needs some touch up, you just take a brush, touch up the paint and start the motor. It blends into the rest like new. So I used it on my master cylinder and the engine heat was enough that it worked there, so now when it needs touch up its a snap.
