I am a certified Cerakote Applicator and while I have Iwata HVLPs and Cam Air 5 stage CT 30 air filter/dryer system what I refuse to is spend thousands of dollars on a curing oven that barley fits one rifle and only costs the manufacture a few hundred to make.
I built my own customer ovens that are very large ( interior curing space is 40" x 32" x 18" ), portable, has very good insulation that hold heat extremely well and can operate up to 1200 degrees F, require very little power to maintain temp, has digital PID and costs less than $400 to make.
