A little "triva" paint story.
I worked at a Chevy dealership in about '68-'69. We had a customer who would come in with a 1956 Buick, who had brush painted his car with the original coral colored lacquer. After it dried completely, he sanded and hand-rubbed the entire car! If you got close you could see the hint of brush marks... but from a distance, it didn't look too bad!
In all of my years since... and being heavily involved in custom paint , car building, and of course the "car culture" activities... I never saw this again! :-)
I still admire that Buick owner's persistance some 45 years ago! :-)
