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.

Sprayed, trimmed with a saw to shape then skimmed with filler, smoothed, refilled etc before a layer of EC primer to take the mould. and result in carbon, not perfect, but this was the first go...

Full credit goes to you mate that's going to look superb when finished. Nice T5 btw ........ I've got a 2003 T4 I need the insulation foam to act as a support, as my intentions are to build on it using resin. I really can't take the chance that it will shrink as Hanaldo mentions. The moulds in question will be for vacuum forming some quad headlight covers, so the measurements are critical. I'm hoping to make different headlight covers, some of ABS and some will be Carbon fibre skinned. So they'll be many many questions about carbon fibre when I get to that stage. That Polyurethane foam you used, what it the regular builders stuff you can get in a spray can ? Thanks for sharing your project, will you show us it completed ? TURK

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
