Thanks for all the replies, I shall be buying direct from the USA. I guess I would like to add my opinion on Poly Fiber; I find that when people don't like using a particular product, 9 times out of 10, they don't have a lot of experience using the product, and they're just not good at using the product. Call me arrogant but that is what I've found, not just in aviation but automotive as well. Personally I wouldn't use anything but Poly Fiber because I like using it. I continually get advice from people why I shouldn't use Poly Fiber products for one reason or another, but I find it easy to use, fantastic to get a very neat finish and absolutely fantastic to paint on. Each to their own, but I will be using good ol' Poly Fiber, Poly tac, mek, Poly brush, Poly spray and 2 pak polyurethane colour coats with flex add. Cheers all.
