I was somewhat disappointed by all the brush marks but most disappeared after spraying with clear.
Next step is to buy some One Shot enamel and try my hand at it myself. I've kind of caught the license plate collecting bug after buying 10 Texas pairs from a friend, 1949-1967. I've also bought a bunch on fee bay including a 1917!
