Problems with materials!

[RustySpoon]

Hey guys,
I've started to build an iron man costume out of thermo plastic, but it's just not a goo idea for the whole suit.
Where can I get the foam to build the actual armour? I'm in the uk but I haven't got a clue what I'm looking for let alone where.
Any help would be great.
I'm in london so I don't mind going out to get it.
Thanks.
Spoon.

Have you tried camping / yoga mats? Their cheap and readily available. Sports Direct is usually good for about £4 a roll, just make sure you have at least one smooth side on the mat

Some folk have used plastazote, namely the LD45 stuff.

You can get it from here... Thames Valley Supplies - Shop - Plastazote
