I have seen a few made using a single locker with insulation and a hot plate. LarryAnyone built one? Show off pics and details!
PLEASE, never, ever bake off any gun coating in the oven that you cook food in. Also NEVER store cerakote or any other like product in your refrigerator. All of these contain isocyanides. Yes a form of cyanide. Not really known to be good for your health.Heck you can use a kitchen oven if you don't mind the aroma. All you need is 300º for an hour. Scavenge a throw-away oven for burner/electric element and thermostat and find a metal container long enough to fit a rifle in.
