oops, my bad I didn't really look at the numbers The epoxy itself is not that strong (that's as strong as aluminium!). Again, the strength doesn't come from the epoxy anyway, but the fibers (be they glass or carbon).

As far as other choices... I'd use epoxy. There is a reason we don't use milk-glue, or lead paint for that matter... Epoxy is predictable (strength) and when a little care is used (gloves, long sleeves, well-ventilated area), should pose no serious threat.

Have you thought about how you are going to seal the edges? /if you wrap it you might ad significant weight.
