Default Bubbled Paint On Master Cylinder

Leaking brake fluid is a common HD problem. The paint on my Street Glide master cylinder / brake lever mount point is bubbled and ugly. I'm pretty **** about my bike, and that irritates me to no end. Any ideas on covers or repaint to fix the paint? Who makes the chrome covers that cover the whole master cylinder? What have you all done? Thanks!

Not that big of a deal to replace. Have done it before for the same reason.

I bought a used bike that had a lot of bubbled paint on the master cylinder. Since I was replacing the bars and having a lot of parts powder coated, I had them do the master cylinder as well.

Yup, brake fluid is the world's best paint stripper, at least DOT 3 & 4 that is. I'm really disappointed that with all the technological knowledge the human race possesses, we can't come up with a brake fluid that doesn't strip paint. Well, DOT 5 fluid doesn't attack paint, but apparently it doesn't work with ABS, so no DOT 5 for you.

I've seen all chrome covers that cover the entire master cylinder and area. Where can I get those? Anybody have one on their bike?

i think i've seen one from kuryakyn. but it was ugly. they may not sell it anymore. but you can get a chrome cover from hd, and a chrome master cylinder. is it worth $650 to you?

Just the cover or the whole master bubbled? If just the cover, get the HD chrome cover. If the whole master, it’s gonna cost you a pretty penny to go chrome or just pull it and replace with a take-off, buy another black one, or refinish.

Gotta get the fluids flushed out the MC and lines every couple years. Also noticed that long term exposure to direct sunlight/ Heat adds to the problem. I stopped leaving my bike parked in my garage on the side stand for an extended period of time. I noticed that’s where it starts seeping in the corner when the bikes tilted over. If I know it’s gonna be sitting for a couple days or more I’ll throw it up on the lift

A while back someone suggested sanding the outside of master cylinder by hand and then using rustoleum satin black paint.
I suggested what i read to someone with a master cylinder paint damage problem and they did the suggested process i had read to the bottom part of master cylinder(not the cover).
Nothing removed from bike but everything was taped and protected from over spray.
Looked good when done and still does after almost 2 years.
