To bake the coating, any constant and controllable heat source will work, even the oven in your kitchen. However, the heated coating emits an odor that might not smell as good to everyone else as it does to you. To avoid problems, I simply bought a large toaster oven for my workshop. It cost less than $100, which is far cheaper than a divorce lawyer. Mine is big enough to handle handguns as well as actions and frames from rifles and shotguns. In fact, it will handle just about anything gun related, except a rifle or shotgun barrel. I found that the temperature setting is unreliable, so I bought an oven thermometer to help regulate the temperature.
