Just caught up with your build thread. You're doing good work and it's all coming together. Many years ago I worked at a wooden boat restoration shop and we used 3M 5200 by the case. If you set a tube on a heater vent in your house for an our or so before using it lowers the viscosity by about 50% and makes it a lot easier to use. Otherwise, like you said, uncooperative peanut butter at best. Keep up the good work.
