So I ran out of the bird feet injector I was using and had to order more. This time I went with Masters Blend after reading posts by others on this site about how they liked it. The problem I am having is the set up time. I mix a batch, put it in the needle, and inject one foot. By the time I get to the second foot the remainder in the syringe is hardened. I know I could just mix 2 small batches, I was just wondering what other people who use this product do. Do you cut it with something? I am storing it in the refrigerator, should I not be doing that?
