Has anyone used Progressive Polymers No Blush Epoxy? Is it better/worse/same as MAS or System 3? I'm trying to keep the costs down and this will save about $100. I've used their sample pack and it seems fine but I haven't used with fiberglass. I don't really want to experiment on a boat that I have a couple hundred hours into but I'd use it if the reviews were good.

Scroll down to find info...(I don't like the website either)
