I have a couple of questions regarding the cerakote process. I keep getting mixed solutions as to prepping the AR receivers surface for application. I hear from some that it only requires that I heat it and acetone it to get all the oils off before application. The other group I hear says I should use Aluminum Oxide blasting to prep it. Blasting materials and medium is something I don't have access to, and therefore, is going to be the crux of whether I do this or not. Also, how many passes should i make on the surface to insure that the coating is sufficient but not too thick? Vague questions, I know, but thanks in advance!
Just for reference, I have a RRA that's going to be my "test dummy" so to speak. I plan on coating the handguard, upper receiver, lower receiver, bad lever, receiver extension. I may decide to coat the barrel black as well. All parts have been disassembled down to their last nut and bolt. After the test dummy and my atrocious painting skills, I may attempt the OBR O_o. |
| Clean, blast with alum oxide, blow off with air, coat, and bake. Once its clean dont touch with bear hands. Wear a respirator when applying. If you get any on your skin wash it off asap. One of my part timers didnt listen, got some on his hands, went and used the restroom. Lets just say he wont do that again lol |

It really needs to be blasted to get the proper adhesion. You can do it without media blasting but you won't get the same end result....the coating will likely fail much easier. Prep is the bread and butter when it comes to coating with Cerakote.
My process...degrease, heat, degrease again if needed, media blast, blow off, spray and cure. |
