I can top that. About 1954(I was in high school)I saw a guy paint his pickup with one of the old fashioned fly sprayers, you know, the kind you pumped by hand, before spray cans were popular. He wanted to avoid brush marks and didn't have money to pay for a paint job(common with people I knew back then, including my family)so he used the fly sprayer. It wasn't too bad except for the orange peel effect,but no brush marks. Paint was a good quality auto paint, red in color.
Wow! REAL car paint. I’m impressed!
