Master cylinders - how to keep shiny?

I’ve just received a nice new shiny pair of brake and master cylinders from Sue Miller [Girling and a good price as usual].

Is there any sort of sealant or “varnish” that one can coat the cylinders with to stop them gradually discolouring - or is it a question of keeping them polished?

A clear lacquer is what you’re looking for to keep it shiny and bright.

Personally, I would paint them a gloss black ? much more impressive.

Thanks Brian - just what I was looking for. I prefer the metallic look!

I wouldn’t put anything on them other than to wipe them over regularly and wipe up any spilled fluid. The laquer will go milky.

Hi

I have put Autosol on mine, it claims: “Restores and polishes to a brilliant finish. Protects against Corrosion and Tarnishing”

Mine is ok so far :slight_smile:

Hello everyone.
Isn’t brake fluid a good paint remover?
If it is it seems to me that painting would be a waste of time.

The best method I have found is to strip the cylinders, mask them up, bead blast them gently then spray with conformal coat as used in the electronics industry. Bead blasting provides a very good key and conformal coat gives a well proven enviromental barrier to most things.

Didn’t I read somewhere on the forum that silicon brake/clutch fluid does not attack paint?
I know the old original stuff we used years ago does.

I use some stuff I got from Carcoon (the car storage people) It’s a spray can of water dispersal and corrosion protection fluid. I spray it on eveything that’s not painted. You can even spray it on brakes:

There is also a similar product called (I think) ACF50 - bikers use it for the same purposes

Thanks for all the suggestions - I will try one or two of them and I shall report back.
