Yep, Lacquer at one time was the choice for show finishes and GM used lacquer on almost all their cars from the factory. All spot paint work was done with lacquer. I did many overall paint jobs in lacquer but most overalls were done in polyurethanes (Amer-flint, Imron). Lacquer had many bad qualities though, Prolonged time in the sun would crack it (crazing),Had to be buffed and it dulled faster than today's finishes. Not to mention having to sand it, it would just roll up and clog sandpaper.Been in the business 40 years, I remember those day well.
