I had to by some parma stuff for emergencies recently and it cost me nearly £8 for 8oz!
I always order 3 bottles of 32oz divelys from RCBoyz and it works out at about £16 per bottle including the shipping! Bargain!
Northy, what colour you wanting? I've got loads of pactra that I don't use anymore. But, otley modelsport do mail order on the pactra paints. thats where I get mine from now that all my LHS's have closed down!
