it is not the west that fails at 80, it is the foam. i just finished the molds and boat for an open 60 mono project. we used the west 105 to sheath the molds and it was fine. we also used some of the blue foam (sm) in some of the ovens and it turned into a big blue puddle.
oh, and the gougeons make west


yes gougeon makes both systems and they market the west to the home-built boaters due to the low amine blush. the pro-set is aimed more at industry, but the amine blush is so high its sticky when cured, but neither system is for tooling?? and you are very correct, blue foam and ovens dont mix <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
