I haven't painted a vehicle in decades, so I don't know what it costs. I was into off roading, so I had Jeeps, a couple Bronco's and a big lifted truck at one time. I was never about a show vehicle, but I did want to make each of them a certain color that looked good from a distance, but I wasn't afraid to go off roading in, or explore a new trail.
In those days, I would use an enamel paint that stuck to anything, and held up good to abuse. It was a cheap paint as far as auto paints go, but it worked perfect for what I wanted.
Yesterday, while I was in Lowes, I decided to buy a gallon of Exterior Valspar Duramax paint to try on my shipping container. I'm about to build a dog kennel next to the container and I decided this would be a good time to cover up the faded red and white paint on it. It's far enough from the house that I'm fine if it doesn't look perfect, I just want it to disappear in the trees a lot better then it does now.
