NOS Booster, use or rebuild?

I ended up sending it out to be rebuilt by master power brakes. Upon its return, I layed a thin coat of fluid film on the brackets, booster body etc to keep the plating from rusting. There was really no pitting at all with only very very small pinhead sized rust spots. I do hope the plating lasts as it's not a daily and wont see the elements. Also, I added 8 plastic washers to the metal to metal mounting points.
I bought this one recently from a member here, NOS Eddy from a 2 year old ad. The same booster kit was a few hundred dollars difference from a seller on Marketplace. The guy at MPB said Midland cores are hard to find. They have/had a restored one on their site, but with significant pitting. Great guy to deal with though!
