I'll be interested to see how your paint idea works out. You'll have to let us know. Are you thinning the POR-15 at all when you shoot it? In the past the stuff I've worked with seems waaay too thick to be able to shoot with a gun.
I'm jealous by the way, I haven't been able to do much with my Willys wagon because I just had to drop a couple grand on rebuilding the transmission in my DD, and I'm going to have to spend another couple grand for tuition this semester. Maybe I should not go to school this semester and just work on the wagon instead...
