Cheers for the heads up on what a 'form' is/how.
The thing with modelzone is although it's convenient everythings a little overpriced, also i'd need to buy a pack of card rather than a sheet, as it turns out i've got some 30/100, so i'm cool there and i really need to get that planked card anyway.
On another note i've ordered the blitzs and took a trip to the lego shop and got those pieces to make the, is it shuttering? (only know the concrete reference). I'll get the instant mold next.
On the subject of the blitzs, they're supposed to have planked sides the zvezda models don't, any ideas 'how to' apart from taking a scalpel to them, can you get a cheap scriber? Is it advisable using it on plastic? I can just see it making more mess than it's worth, what do you think?
Cheers for all your help guys.
Edit. Aha, you can buy plastic scribers, that'd mean i could make my own planking...
