doing an electronic project soon and im building a simple vacuum forming machines for my case.

something similar to
http://www.instructables.com/id/Make-a-good,-cheap,-upgradeable-sheet-plastic-vacu/

was wondering if anyone has any experience in this. i mainly want to know how i could color my plastics. in the instructions it says they just purchase plastic signs and melt them. so i guess my only chance would be to find some solid color plastic sheets or find some way to spray paint them.

(this is going to be used as a hands on gaming device so the paint has to stay on it and not on your hands!)

thanks for reading. hopefully mods dont close lol after all its about colors and crafts which is all graphics and art!
