Anyway, they say it can be used with glass, like a less brittle 105 w/ hardener- or as an adhesive. I think I'm gunna try it. If it works as advertised, G-flex (w/ glass) should be somewhat less prone to cracking under impact than straight ABS, and it should be WAY easier to wet up glass with G-flex than with ABS slurry.
I'd love to hear some edumacated guesses as to how this stuff might work with Kevlar felt (mostly cuz I have a bunch of felt).
So, somebody must have tried this stuff already for Royalex repair. I'm just not comfortable out on the bleeding edge...
