Its actually called "leap frog green". Its a cheap Valspar paint, just like rustoleum but tintable any color. I bought a gallon of it from Lowes for $26, it was the gloss (not high gloss). The black on the other hand is just plain old black gloss rustoleum. I used a cheap $20 Harbor Freight paint gun. There are imperfections but it came out as a good 20 footer.
I'll be re-doing it in a few years with real auto paint but thats after alot of other body mods. The hotwheels emblem on the side is just photoshopped as of right now. I'll be laying down a few coats of clear on the paint and will integrate some yellow/gold flake to the clear to make a ghosting effect for the hotwheels emblem and flames.
