Weldwood Plastic Resin is very similar to Urac, both urea glues, but is a dry powder that you mix with water. I have used it sucessfully with hickory backings on bows with good results.
Does it need heat to cure? what about moisture sensitivity and heat? I sell/trade and give away some of my bows so I want them hot car safe. That is why Urac shines. I don't need to gt it as hot as a regular bow epoxy in order to not worry about delamination in a hot car.
I love its consistency, the smell, everything about it. Darnit.
