Thanks again guys for all the great feedback.
Back when I built this model, only the very top echelon of model car builders were actually using lacquer paints on their model cars. The best selection, in quantities that were appropriate for model cars, came from the Metalflake brand of paints (many colors were sold in Pints, presumably for motorcycle builders/customizers and van murals.)
A number of my late 1970's contest models, and those of my competitors, used Candies, Pearls, and Clears from Metalflake. The clear, in particular, was just about the only one at the time that stayed clear (vs. yellowing) over the long run. Ah...the memories.
