Last night I successfully fiberglassed the inside of a rolled sheet of laminate that will eventually become make a 15" OD upper cage for a truss tube.
I had good adhesion - the epoxy fully penetrated the fiberglass cloth. It cured well with no bubbles in the cloth and the cage seems to be pretty stiff.
Question: Do I need to add a second coat of epoxy? Does it add any additional structural benefits, or would that just add more weight? In other words, assuming I got a good bond with the first coat of glass/epoxy, do I gain anything with a second coat?
For what it's worth, I plan on flocking the inside of the cage, so there would be no aesthetic reasons to add a second coat.
Thanks.
