I'm about to have my master cylinder rebuilt on my '60. The judging manual states: "Master cylinder may appear painted with black preservative." I assume if you elect not to paint with black preservative that cast iron gray finish is the other option. Can this be a baked on gray finish to appear like natural raw metal? Thanks.

Re: '60 Master Cylinder
Dave...
The master Cylinder was completely unpainted, raw castings, some may appear painted semi-gloss from the black out process. I would not recommend a a baked on gray... I have seen "drivers" painted completely black that would be better than gray. -
Re: '60 Master Cylinder
Dave,
My 60 was coated with some sort of black preservative paint that looked almost like shellac, it was crusty and very brittle It was clearly a dip applied coating because of all the runs. I repainted it with some black DP90 primer when I restored the car, and never took any deducts for it. I would think that a bare, unpainted MC would fare the same, but the "Cast Blast" grey paint would probably take a deduct.

Re: '60 Master Cylinder
Another option would be to have it powder coated in satin clear. I've had several natural cast iron pieces coated and it is impossible to detect with a visual glance. Very tough finish with the bonus of being more resistant to brake fluid than paint.
On the rebuilding of your master cylinder. Alot of folks use White Post, they resleeve in brass and finish with black Imron paint.
I've found an alternative that uses SS, very reasonable in cost and has been in business 30 years. Karp's Power Brake Service, http://www.resleeve.com Ph# 909)985-0800. SS offers advantages over brass and brakes are all they do. I've sent them my wheel cylinders for sleeving and will send my master cylinder when I find a correct Delco.Comment
