There is another option, since you are not trying to match a specific automotive color.
Farm tractor paint. Not being funny.
Really good paint, high gloss, easy to shoot. Add the hardner and it drys quickly and weathers well. It actually goes on quite well with a brush but I couldn't bring my self to do that on a truck.
There are lots of colors. I always use Tallmans AG Specialty paint (made by Van Sickle) $60 a gallon
On line through All states AG parts.
