Another method, and much cheaper, is to mix plaster of Paris with latex house paint.
(A good chance to get rid of all those leftovers.)

I don't know how strong it would be, but it's easily sanded and can be painted. :huh:

Here's a method - but I think they're using a different kind of foam...

Maybe do the plaster and paint method 68 gave us and then do the fibre glass sandwich on top of that... ?

I have this story in the original magazine article... somewhere...

Maybe the answer is to switch to the different foam - urethane foam...
Unless you've already got the styro shaped... then try the epoxy resin.

From the FAQ section of that site:
"Polyester fiberglassing resin will dissolve polystyrene foam (Styrofoam) on contact. If you must use polystyrene foam, you'll have to switch to epoxy resin to avoid dissolving the foam when the resin is applied. But epoxy is about three times as expensive as polyester, and polystyrene foam is much more difficult to work with than urethane. If you switch to Styrofoam and epoxy, you'll hate the system. If you stay with urethane foam and polyester resin, you'll love it. "
