Polyurethane sheet/blocks where?

[Badgrizzly]

Hi guys anyone know where together some polyurathane sheets say 3 inch thick. I need some to make shape for my wings for my car. I intend to carve them to shape and sand them the cover in matting and filler to create a pair of 40'style wings for my roadster. Cheers Gary

Why use poly blocks, just buy some 2 pack foam and cast your own roughs then user filler to finish, foam available from here:
