Thanks All, The test results seemed to be geared towards no finishing results, and since I plan to paint and/or varnish, a paint or varnish test would seem to help more. The one thing my local boys said about MAS was that it won't wet out fiberglass very well, what exactly they mean by this I'm not sure. Since there were'nt any cut and dried responses, I guess I'll have to choose on a personal level. There seems to be more MAS users than West System users so advice will be more accessible from this and CLC's bulletin boards. None of my local suppliers or their employees would appreciate a phone call at 10:00PM with a stupid question, but there's bound to be one of you available to ease my beginner's jitters. So I'm leaning towards MAS, unless of course... who knows! Thanks again! John
