Re: are we crazy not to try Epoxy alternatives?!
I constantly use PL Premium construction adhesive in place of epoxy when I can, when it is safe and effective, and when it won't spoil the looks of the application. But for critical joints and coating I still use quality epoxy.
Decades ago there were some posts here by Chief Red Elk about using various glues with polyester fabric as a sort of poor-man's fiberglass, but I don't remember the details. An interesting concept but I'd want to do a lot of testing before trying that process on anything important.
