Sprayed or dipped?

[Lynn]

Definitely not dipped. All the passages would get paint in them.

Sprayed, but very lightly. I have never seen one that had paint runs, and have seen some that definitely did not get full coverage. Gotta remember, GM didn't give a hoot about what that master would look like in 10 years. Just needed to be nice enough to get it off the show room floor.

Here's one on a '69 Nova SS prior to delivery. Some runs, looks dipped to me. If it was done prior to machining there weren't any passages.

you'll get dinged for it in Frederick if its not natural, what can I tell ya LOL. Guess we need to tell the guru's there. I'd love NOT to have to strip my master cylinder

[Mr.Nickey Nova]

All the guru's that judge don't know everything, but they think so...

[Lynn]

You may be correct William. Although from that pic it is difficult to tell if that is a run, or if someone spilled some brake fluid when filling it up. Not saying it isn't a run. Besides, even if the passages were not machined, you would have a problem with paint in the reservoir. Paint and brake fluid don't get along very well.

The finishes I have seen certainly don't look like other dipped components, like the cross member or motor mount stands. I have found dried puddles of paint on those, and would expect the same on something as oddly shaped as a master cyl.

Lot of this resto was done to mid 2000's knowledge and acceptance, and frankly, scoring too even at MCACN. My car scored 993 in 2009 there, but with numerous errors when it went up against the big boys in Frederick 2015. Say what you want about them, they know their stuff

In Jerry's book its says black or natural on the brake reservoir, now its been universally accepted as natural. Chrome tips only came out with May 15th etc etc. The subframe pitting and prep on this car goes into the &quot;wtf were they thinking category&quot; </div></div>
Are you sure you are correct about them not accepting black master cylinders ? That is knida hard to believe.

[jl8z28]

They say it was black I been through it

Here are some pictures of a NOS ZA coded master cylinder. Not sure what it fits.

What universe did this consensus come from. Most of the original unrestored cars I've inspected/ certified have remnants of black paint on their master cylinders.

If you were looking for an assembly line correct restored car this car would not qualify. If you're looking for eye candy well....
