I was joining two wing halves yesterday and mixed up a large batch of
30 minute epoxy. The temperature in the garage was about 90 degrees. I had just finished coating the spar that joins the two halves and had inserted it into one wing half and was coating the inside edge of the wing when I noticed the epoxy was already starting to harden. I had just enough time (about a minute to coat the second half and join the wings. The meshed together INSTANTLY! I could not even remove the excess epoxy with alcohol as it had set up so quickly. Word to the wise here. If you are using epoxy in this hot weather, bring it to room temperature in the house first. After I set the wing in place I looked at the epoxy cup and the chemical reaction of the epoxy in combination with the heat of the garage had melted the cup!- posted
