I am rebuilding the front master cylinder on my bike and while it is apart I figured I would paint it. I have removed the loose power coating by using a wire brush and cleaned off of the corrosion.
Any one have any good suggestions for repainting it? I figured I would prime and paint using rattle can but I am looking for suggestions.

thats what i would do. i would sand blast it first tho. and or lightly sand with a 1000 or 2000 grit so its not all scratchy. then prime and paint with a good quality paint.

If you are going to be rebuilding it, I would have it media blasted and powder coated. Then rebuild it! brake fluid is not always nice to some paints. You could also polish it instead of paint.  |

If I polish it won't it corrode after a while?

If I polish it won't it corrode after a while? Like anything aluminum it will corrode some and you may have to polish it every so often but look at all your other parts on your bike that are aluminum that you don't do anything to. |

if you have it all apart, powder would be cheap as it is such a small part and it will last unlike most anything that will come in a can. This is why many companies use anodizing back in the day.

I like the polishing idea. It is mostly there any way to what a little more scrubbing? Thanks for the ideas.

Is yours anodized? If so you can use this method that I wrote up to remove the ano. indianapolisvintage.proboards.com/index.cgi?board=restoration&action=display&thread=33If you don't want to submerge the cylinder in the acid, you can mix up a very small amount (1 tablespoon to about 1 cup of water) in a plastic cup (not Styrofoam). You then, while wearing rubber gloves dip a rag or old sock in the solution and wrap it around the part for 30 seconds or so. keep doing that until all the ano is off. DON'T BREATH THE SMOKE! Then just polish it. |

It is not anodized, it was powder coated. The cap is anodized but it is in really good shape and I was going to leave it as is. here is how it looks after the polishing job I did: Attachments:
