I do my best to try and keep a wet edge with the epoxy, so I all bonds chemically. here, the epoxy I used to make the fillets along the sides gelled and the thin scrim layer on top of the balsa had areas that where disturbed, and the fibers stuck up and then the epoxy gelled like that. the result was that my glass cloth would not lay down, even though I had been keeping a wet edge during the install. I had to grind these ripples out later
