Epoxy is, in my opinion the best medium to mate large resin parts together with a life grip. SG’s will hold but if something happens the causes a side force they will fail. Not so with epoxy. It was also better a filling gaps in my opinion. Lay it on a little thicker where there was a perceived gap and GAP BE GONE!Why the epoxy Don, did you have problems getting the two halves to stay together or do you want a strong enough body just in case it fall hard on it's maiden flight.
