Expanding foam for mould, solid enough ?

I'd like to know what the difference is between that, and the 2 part stuff available. I understand that the 2 part stuff may be 'closed cell', probably making it harder. But can I get away with using the normal aerosol stuff usually used for insulation purposes ? I'd like to spray it into a form ( female mould ) about the size of a shoe box, then demould the expanded spray foam, and then brush on layers of Pattern-Coat Primer to make it harder to use as a main male mould.

I haven't bought anything from there yet but I'll let you know how I get on. I'm obviously not trying to drive business away from EC, after all, it's where I buy all my products. But somethings can not be shipped because of it's corrosive nature. So I have to find places local to me ....... and any other members that may be in France. > www.formx.fr The good thing about this find is, they have a vast selection of the 'Foam-It' range. TURK

Actual PU foam (not the aerosol stuff) is closed cell, so the pattern coat primer won't harden it at...
