Large smooth fiberglass? how?

[adam_brandejs]

As a recent grad, this is my first embark onto large sculpture (previously no space)
I'd like to create a series of a few large sculptural peices using fiberglass. but I want them to be very .. smooth, not round, but say a thick piller, what's the best way to go about creating large flowing shapes, without getting incosistency in the surface.

like a car... it's smooth and round, but flat.... I'm having trouble trying to describe this.

is the best way just to sculpt in clay, (I can's ever seem to sculpt large srfaces perfectly consistent in clay) then mould, then fiberglass? or create a skelitin and stretch a sort of fabric over???

Thanks!

I would sculpt in clay, make a mold, and then cast in Forton MG. Google Ball Consulting and you'll find the forton. Its super easy to cast...thin face layer or two followed by a layer of fiberglass. Then you can sand down any inconsistencies for a flat surface.

Many sailing boat hulls are made of fiberglass. Perhaps you can learn from boatyards building these. Some information may even be available on the web if you can do a search say with Google.

My guess is that the molds are made of wood. If the shape you want has single curvature, like a cylinder, you can just bend a piece of plywood for it.
