Mix a 50/50 of each color to make a custom hoof support that has a durometer of 35 shore. Works well with CES soft pellets to further create a softer support environment when needed. Very durable and wears well when exposed as well as under pads or bars. Set time is 4-6 minutes at room temperature. Keep cool during the warm season to prevent early set up. Works great for creating foot molds as well.
