I use KG Gun Kote out of an air brush and bake it in my homemade ghetto oven.
I built the oven for $40. Works awesome.

I can heat it from 200*-500* F and it is consitant in heat top to bottom with 10*.

I wrapped this in insulation: Its just ducting bolted to a $15 electric 5th burner with an adjustable thermostat.

I plan on doing my rifle barrel and action in the oven as well since it is so long.
