I just found this thread while doing a Cerakote search. I just got done installing an upright compressor, copper airlines, paint booth, and blasting cabinet in my garage. I also built a curing oven out of a 14 gun cabinet, oven elements, a PID controller, thermocouple, duct board, and high temp sealant. If anyone is in Oklahoma, let me know and I can meet you somewhere and blast the stuff for free. I spent quite a bit for this set up and wouldn't mind helping someone out and feeling like it was not a waste of money. Plus, I am running out of things to blast and spray. You can also contact monument companies that make headstones and see if they will blast it for cheap. They use blasters to etch the headstones. If anyone has any questions on how to build the oven or where to get blasting media from, feel free to ask.
