The guy I bought the 50 2 ton from has a 40x60 pole building in his yard where he keeps his "toys", and as his wife was in the house looking for the title, he showed me his collection.. from 30's Chevrolet cars to a '54 Chevy pickup (and assorted Dodge and Fords).
At least three of his vehicles he painted in his lawn with rattle can tractor paint, then went over them with some sort of clear coat/gloss.. and made a point of saying, "Here's the paintjob I paid $2,000 for.. and here's the paintjob I paid $150 for"
If you're building a trailer queen and going for the big cash prizes, by all means, get the high dollar paintjob.
But if you're just building a local show, knock around town fun truck.. and you have enough sense to pour water out of a boot with instructions on the heel, then paint it yourself, man and save some buku bucks.
