Here is one video, the people who posted this one (http://www.freemansupply.com/ ) have a great series of clips and if you live in the USA, an online store. http://www.youtube.com/watch?v=WQkzWvHRdZ0

(From a friend:) The stuff I use is mostly Alumilite brand, I get the white solid plastic (they have rubbery and foam plastics) as well as the black dye, it only takes like 2 drops of the dye to make parts black. Decent hobby shops should have this as well as silicon. You will also want demolding spray (its essentially a Vaseline aerosol), for me that was the hardest thing to find.
