I know there is a difference in Canadien dollars and US dollars but what you paid still sounds very high. I get all my fiberglass and epoxy from USComposites in Florida. The shipping from there to where I live, nearly 2000 miles, is very reasonable. I've never had any problems with their 635/556 blushless epoxy. It is a slow epoxy. I've also used Raka with no problems. It's a little faster...and costs more. Shipping was about the same. Hope you find a suitable source.
