Its about 7 or 8 different shades Gene's fade jobs are a closely guarded secret I could tell you but then I would have to kill you......
I did a paint job on a scale model for a carshow 7 years ago that was eerily similar. I used 3 different yellows. Pearl in a clear and about 3 varaitions of pearl with the yellows. The yellows were solids and metallics.
Unless the red job is equally crazy I can't imagine why you would repaint it. That was the only truely good Monster Garage episode.
Looks to me like: 1) a White base 2) ..with a transparent gold fade from the bottom(could be a "kandy" gold color, but some of the off-the-shelf transparent yellow oxide toners can look really similar when mixed with clear) .....possibly with some gold pearl suspended in it. 3) ..then a little bit of transparent orange fogged on along the lower edges 4) Then a couple coats of pearl-in-clear over the whole job (probably gold pearl, but i think I also see a tiny bit of sunset red) ....then clear over top. Whew, i'm tired now.
