Check out Gun kote too. While not as good as cerakote, I've had really good luck spraying it. I'm definitely not a painter, and I've had great results. Its very this as well so no tolerance issues.
I would be wary of durakote. Not saying its bad, but its thicker, and doesn't wear as well.
Here's a quick picture of my budget oven.....
Not pretty but it does the trick!
I apologize in advance if this post is in the wrong spot but what kind of coating do y'all use? I am looking to get my AR coated in OD green and have only really looked at Cerakote and Duracoat so far. Any cheaper alternatives out there that someone has had luck with?
Thanks!
