<div style="margin: 0in 0in 0pt"><span style="font-size: 9pt">I was attaching the two halves of the wing using 30 minute epoxy to give me time to center the halves properly at leisure before the glue sets. I made the epoxy mix and applied it to the two surfaces and started to fine tune the centering when I started to feel that the glued joint was actually getting harder to handle very quickly. I knew something was wrong and adjusted the two halves as best as I could and held themtogether for several minutes .Well, it turned out that by mistake I have used 30 minute epoxy resin witha 5 minute epoxy hardener! The joint seems very solid but do you think it will deteriorate with timeor would it be any less strong than a joint glued with the proper mix?</span></div>
