Review on 🌟 Discover the Superior Performance of FOAM Rigid Polyurethane Foam: Free Trial Available! by Jeff Westra

Very difficult to dry like chalk. It takes a minute for the foam to start, it's easy to add too much to the first bite. I used 5ml for each part and it turned out to be too much for the printed part. All I did was add both pieces to the piece and shake it, put tape around the hole to catch the overflow. Happy with the structure and strength added to the part.
