i understand why this person said this and if the epoxy fills the holes there is no real strength loss, the problem is gettign the epoxy to fill the spaces you cant see, get to or get glue to after you slide it all to the back.if you are really bent on strength the mix some fiberglass strands into expxy and spread that inside. but its still usless, your gonna snap the wing at the middle of one of the halves before you destroy a properly glued brace. also if you want real strength get the good spoxy the stuff that you mid 4 parts resin to 3/4 parts hardener, this is much stronger and great sruff to glass with also it takes ages to dry so great for seapage
