We run Phat Bodies from down south .. we don't tend to do so much in 10th off road these days ... 12th scale being more our thing but design and make all our own moulds
If you're looking for a quantity of polycarbonate try Brissco in Bristol .. they're very good and supply us with loads ...
They stock Macrolon in 1mm thickness which is very good and forms well or can source Lexan in 0.7mm thickness which again is some of the best quality available ..
I'd stay away from the cheap stuff as qualities not so great .. and don't bother with PetG ..
If you need a smaller quantity get in touch I'm sure we could sort you out with something ..
