Thanks for your Comments guys, and its good to see you on here Danny !
And Hello Jamie,
Here is some of the Styrene that I use called "Plastistuct" I have also used Evergreen, and both are made in the US.
I get my styrene from two places, my local model shop and online from a company here in England called E.M.A
they are based out of Sheperton "they supply the effects film industry"
Ihave used them since I was at collage and at work, and they do supply world wide, However if you just go online.
theres plenty of places to order this stuff from, although I will say its not cheap !
I use Plastic weld to "melt" the parts together
and I use a fine Dropper to apply the weld as I have greater control than you do with a brush....and its less messy and wasteful !
Hope that Helps you out a bit Custom Creator,
All the best,
Barry.
