I was working on my PML kit and decided to foam the fin can and it cracked the QT? Has anyone experienced this with QTs? I know you don't foam cardboard tubing, but I never would have expected this to happen.
Using the small mixing cups I used equal amounts of each parts A and B and added 5 drops of water to part A. Mixed the two parts together and poured. It foamed up nicely. I waited until it set up and then made the second mix, which is all it needed.
