Mold for a Fiberglass Cast


To anybody that has cast something in Fiberglass, what did you use as the mold? I'm not quite sure what to use, because I would thing Ultra Cal 30 would make removing casts with undercuts near impossible, because neither the UC30 or the FG would have any flexibility. I want to make an AzBatz helmet this summer, and I'm thinking about going with Fiberglass cause it sounds the strongest, but I wanna have an idea about what I have to do before I start.

part of the key is eliminating undercuts in the sculpt or in the way the mold itself is made. you can use a flexible jacket mold of latex(will shrink over time) or silicone (can get very exspensive). lots of times, the molds themselves are gel-coated fiberglass.

All of my fiber glass pieces come out of silicone molds. Yeah, silicone is expensive, but if you want the best looking pieces, silicone is the best way. Don't settle for less.

Thanks. Now I have a few more questions. First off, where is the best place to get Silicon? And second, I don't know how it's used. Does anybody have a tutorial, or know where I can find a tutorial on how to use it? Thanks

Burman's Foam sells silicone and also includes instructions in the box on how to mix the silicone with the catalyst properly. Once you got the idea down, let us know what you are going to be molding and we can help you mold it properly with a jacket and all.
