: trying to lay second layer always has fibres pulling out of glass making mess
: of llong strands and bunches of fibre when wetting down. going to have to
: let set and sand down before finishing...

Hi Scott, you're preaching to the choir I know a builder who taped the edges and then epoxied around the tape... he trimmed off the tape after the epoxy cured. Most of us just try to ignore them; it seems like fussing makes them worse. The tight weaves tend to fray a bit less I think. A cabinet scraper or the back of a utility blade will take the worst threads down pretty fast; sand as little as possible. For multiple layers I generally let the first cure hard and scrape/sand away any imperfections before doing the next layer; it works pretty well that way. The mechanical bond is plenty robust.
