Bob, not sure what reason there would be to clear any of them, they weren't shot with clear at the Pontiac engine plant. Neither were radiators shot with a gloss black so shiny their tanks looked like hand rubbed lacquer...

The formula you have listed as the Pontiac Power Formula, is it the one Horst Fiedler contributed? If so, it should be the one Lars had published in the Legend in the late '80's. That is the formula I had mixed several times in the early 90's- late 90's & put in cans. The last time around, had a low mile pair of valve covers color analyzed (these had been removed & placed in a box for an older pair of Cal Customs in the Summer of '71). The mix was again, very very close.

As we know, the finish out of a can is not as nice & smooth as it out of a gun, so I'm glad you are going to shoot samples out of gun. I should have another pair of original valve covers off a 4,000 mile original '72. Know I still have the original engine out of that car & it has not been exposed to setting outside in the sunlight. Not sure if those components have had enough heat cycles to color shift or not. Was not concerned with that when I bought that particular Lux LeMans for parts.

Heat cycling brings out more of a green tint & thats is what we are seeing in one sample.. The other extreme, I often run across on the '71-early '73 paint is with the hood off on a parts/project car, or an engine setting in a core pile, the engine enamel tends to fade (bleach out) quite quickly.
