I have run across so many old cars, that have been painted with a brush. I have even talked with old men when I was younger, that swore by, and still painted their cars and trucks with a brush. I know of one guy who painted his Panhead with a brush and wet-sanded it and it looks great. About a year ago, I lettered the doors on a 1939 International pick-up that had been brush painted three times over the years by it's 90 year old owner. I guess the point is, it can be done, and sometimes quite well. Old Lacquer paint, a good brush, and alot of finesse to remove the brushstrokes.... A Saturday afternoon well spent.
