Casting Question

Okay, I searched the forum, but I didnt have any luck. I want to know what rubber/material people normally use to cast items in fiberglass. I experimented with some clay, and that was fine, but I'd like to know what rubber material people use, where I can buy it, and any other usefull info.

Thanks for the help in advance!:)

Silicone Rubber. Tin cure, or addition cure (platinum). Just google those terms for further explanation.

For starting out, I'd go to Smooth-On. A supplier of many useful materials. They also have a helpful tech support staff that can answer any of your questions as far as what they recommend for a particular project you may have in mind.
