Brake fluid resistant paint?
Hello-
Is there any rattle can or brush on paint that will resist brake fluid? I have a bare metal brake booster and master cyl to paint. What primer do I need to use also? Any tips appreciated.
Thanks,

Brake fluid resistant paint?
[updated:LAST EDITED ON 10-Jul-02 AT 03:16 PM (EST)]Absent powder coating, the answer is no.
however I have used POR-15 on master cylinders(exterior only of course) and it seems to work real good, and stay on. it helps if you wipe off any excess when it spills, because eventually brake fluid will eat through it.
now of course I am only speaking of dot 3 fluid. if you make the switch to silicone (dot 5) you will have no worries about paint. (dot 5 doesnt cause paint to lift)
hope that helps

Thanks Drew!
>Absent powder coating, the answer is no.
I thought that some of the epoxy paints might work, and I was wondering if anybody had experience with them.

I would have to order that in so it would take tooo long. I also don't have any spray equipment at the moment.

I usually wipe it off then rinse the area with water.

My system has DOT3 fluid in it now. When I rebuild the truck (soon) I was thinking about converting to DOT5. I will check in the Suspension forum to see what is required to convert, at least when the search function works again.

Brake fluid resistant paint?
Epoxy paint will work if it has time to dry/cure properly even w/o primer.
Now the real question? Why is brake fluid getting on the outside of the unit? I would concentrate on the leak first. All of my Fords (3) are dry on the outside.

Brake fluid resistant paint?
The unit is not wet (at least I hope it stays dry). It is a newly purchased remanufactured power brake and master cylinder unit that is bare metal. The old booster unit was painted but it had been exposed to enough brake fluid over the years to blister and rust a little. The old master cylinder was bare metal and heavily rusted. I am trying to prevent rust on the new unit. The metal on the new booster shows some pitting from old rust. I was looking for a paint that would resist the worst attacks of DOT3 or 4 brake fluid. Some seepage can occur around the master cylinder bore in use. Also the gasket around the top of the reservoir can seep a little on some units.
I will check at the local paint store to see if they have any epoxy paints.
It looks like the DOT5 brake fluid is great stuff but every rubber seal and part in the brake system would have to be replaced to use it. I think I will just use DOT4 for my truck rebuild.

aervoe.com, -Interesting site, I added it to my favorites. -Thanks!
I have been thinking about using a pie tin to test several different readily available coatings that have a chance to work. Spray each pocket with a different paint, then dump a little brake fluid in each to note the reaction over time. Geee, a science fair project! -hehe

I know this is an old thread, but thought I would add a note. We recently introduced Eastwood Brake Gray which is an aerosol that is resistant to DOT3 brake fluid and temps up to 400F.
