Daryl S, most of the PC coatings are best if run at 400 degrees for a full 30 minutes. A good test is after they have cooked and cooled down to take a hammer and on a concrete surface smash it down flat and see if the coating flakes off or if it stays on. If cooked and cured correctly it will stay on and just be a flattened boolit.

The temp on the way to 400 for 30 minutes.
