My best advice is to watch out for the epoxy fumes, and try not to get fiberglass shards stuck in your arm...they sting and dont go away for a while

. Oh, and make sure you get the fiberglass wetted out adequately, it should turn sort of clearish...however, dont get TOO much epoxy into it or it wont be as strong, the strength comes from the fiberglass, not from the epoxy.
