Gosh, that machine looks a beast

hard to imagine it's on a heng long/WPL chassis.
I have a double question involving your bumper paint if I may.
I know the bumper paint is very good, but I don't know anything about printing. I've spied something large Woz is selling on his shapeways site, I really want it, but it only comes in white versatile plastic, I don't have a clue what that is, I'm guessing nylon, therefore, should I either ask Woz if he can print it in something else, or do you think the bumper paint will work on that type of plastic?
Thanks.
