This has been thrashed out a dozen times, so my apologies to those that are thoroughly bored by the issue. I couldn't get the search function to do anything more than spin its cyber wheels.
I'm about to start on an new project: a 26' strip built and sheathed power boat designed by Michael Mason along traditional Nova Scotia Cape Islander lines. This is intended to be a commercial venture (note that I did not say profitable commercial venture) so out of respect to the no-self-promotion rule I will go no further.
However, I'm interested in opinions about and actual experience with the various brands of epoxy that are on the market in terms of ease of use, results in the face of a less-than-ideal application environment, quality of technical support, variety and appropriateness of fillers and additives, apparent toxicity and so forth.
