Anyone used fiberglass mold to cast their wax model?

Is it possible to use a fiberglass mold to pour a wax? If not I suppose I'll have to pour a fiberglass model to make another mold from. Any suggestions or experience out there?

I can't see why not. Why fiberglass, do you need more rigidity than you might get with rubber? What scale are you working on?

I've used fiberglass to reinforce a mold, but the face of the mold was still rubber to allow easy wax release. I'm not at all sure how well wax would release from fiberglass itself, though.

I thought ck might might encounter some problems there. It's definitely not a material that would work with all waxes and parting agents. I still wonder about the scale -- 10 mm? 2 ft?

wax release on fiberglass

Just release it REAL WELL and there should be no problem at all. I would use a silicon spray for a release as it seems to work very well when wax slops over the mold onto the fiberglass.
