Some good info on what not to use Kelly. For coating and bonding I always use West System epoxy and their fillers. It is slower but predictable.

The suggestions forwarded by Mark G and Kelly are spot on.



Polyester resins and lacquer (volatile) solvents etc. make short work of styrenes.



I also work with this stuff in the film industry and we overcoat the rough forms with epoxy resin (and glass mat if strength is required). You can then apply Bondo to your heart's content to fill as needed.



The expanding polyurethane wood glue (Gorilla and others) is excellent and renders a decent, strong bond by creeping into the voids between surfaces. There is also a specific polystyrene cement which is like contact glue and might be cheaper than other adhesive suggestions; ideal for assembling flat sheets.


Lastly for a perfect finish on your form you can spray a high build 2-K epoxy filler-primer over the form, and easily sand it down to a superb finish. We call it "MS Primer" in these parts...

Default Questions on building a styrofoam buck.

Has anyone tried "CASCO contact 3880", water based CC. Says it wont eat foam?
