But any comments on the Lockheed booster finish?

I don't have a picture, but I hit the cast iron section of my Lockheed booster with some clear coat when it went back together. Not much, just a coat, not even so much as to make it shine so no more than a dusting of the stuff. Six years later it still looks very good.

Is that 2K clear?

The cylinder body was never painted. It was left as cast.
The vacuum body pressed metal parts can come in 2 types of finish.
Early cars had a zinc plated finish in a siiver grey colour.
Later cars had a zinc plated finish that was passivated and this gave it a pale gold colour.
Passivation is an additional anti corrosion process to provide better rust protection than zinc plating alone.
I had the booster parts replated several years ago as it started to corrode at the bottom of the clamp that holds the 2 halves of the vacuum cylinder together.
This was caused by water collection at the base of the clamping ring which had the clamp screw positioned on the side and not the bottom so water couldn't drain away properly.
It was like this from new.
So make sure you position the clamp at the bottom and not the side.

Zinc coating is the only real alternative that looks close and comes in Blue (silver) and Gold passivated. The Gold is too gold and the blue is too silver, so we don't really have a spot on solution.
