GRP sheet?

[Cr3Ad]

Hello just throwing this out there but does anybody know of a place where i can get GRP sheet. near to bury, manchester.

i know its on ebay but looking for this as a project to hopefully start very soon, tomorrow in fact

if any body knows a place the info would be fantastic not many model shops left around here now, they only seem to stock the cars not really for the diyers now.
thank you
