Best Quality mold materials~

[CommanderBrace]

Has anyone used the resin casting method repeatedly? I know certain kinds of mold making materials will shrink over time, and there are better ones that wont shrink as much (more pricey~). However, I've heard of using urethane rubber as the mold material, which I'm unfamiliar with, and I'm sure there are other types as well.

What kinds have you guys used, and what level of success did you achieve with them? How long did your molds last?
