I repainted mine some years ago with spray cans. I used Krylon acrylic enamel. I searched and searched for a green metalic and finally found one that nearly matched my Kelly Green metalic and a color that looked similar to a pearl white. I never did find out exactly what it was, the code just said "white" and as you know there's a million whites. And as it was said, I think it was HotRodPC, that prep is everything. He's right.
At the time I worked for an airline and I went over to the paint shop, not ever painting anything as big as a pickup truck before, and ask them what to do for prep. So I did that, after taking off all the trim, taped it all off, and started painting. It was a two tone paint scheme as '74 C10's mostly were and it took 13 spray cans of green metalic, and 11 cans of white, all gloss colors. And I don't know about some people's experience but it dried even and keeping a close eye on it did not have any thin spots form it drying uneven. Follow the directions to the letter. It dries fast so you have to work fast, but not to fast or you will get a thin place, to slow and, god forebid a RUN! I hate runs and sags. And I have painted plenty of motorcycles and tons of car parts and even bicycles to for many, many years in every color but never a whole vehicle. But I ran into a wall on the left front fender where I ran out of green.
So I went back to where I had found that perfect color and they were out. So I looked for something as close as I could find and the nearest thing was in laquaer. Well, know one told me you have to clear coat laquaer or it will turn dull on you within a few days of drying. Well, it sure did and that was the only part of the whole truck that didn't look great. The guys at the hanger couldn't believe I painted the truck with spray cans. I never had the money for a compressor so I had to learn with spray cans and got pretty good with it. I ain't no LA Lowrider painter by anymeans.
