Have you considered the Rustoleum textured paint?

My old truck almost got some of the silver hammered across the bottom (to hide the copious flaws). Then again, that whole vehicle was a shade-tree experiment in body work gone wacko. I had this white S-10 Jimmy sitting in the yard and my dad and I were wondering what it would look like with the back cut off. So, we did it. We also threw a Series I 3800 in it, too.

I drove it without doing anything to it for about a year like this. Then I gave it to my little sister and she drove it for a year. Now, it's sitting in my dad's yard again waiting for it's next lease on life. The cab mounts have rotted away, so it'll be something completely different again next time.
I don't have any current pictures of it with the 255x10's on the back, but they look cool. It also has a 2000 S-10 bench seat in it.
That terrible blue was CHEAP. We got some of that industrial "smurf blue" and mixed it with a little black before mixing with laquer thinner to spray on. Yup, low tech. To paint, we just watered the lawn to limit the dust and sprayed out in the open. It turns out that mosquitos sand off without leaving too much of a mark
Would I do the same to my VX? No way! It was fun to do it to a vehicle worth less than $300, though.
Photoshop is for the weak! Viva 'la sawzall!
