I have never used cerakote. I have used duracote though.
I have read several post where people like cerakote better. I have an airbrush from my duracote work. Is their anything special I need to know before trying cerakote? I see several videos where guys cote the inside of the ar's. Not sure I will go that far. Is it ok to cote the gas tube on an ar15? |

Quoted: I do not have a bead blaster. I have not going to do the oven treatment. Was going to try the air dry method. However will cooking them in the oven affect cooking food in it later. could be an option. What about cooking plastic? |
| I do a lot of cerakote for my hobby and will tell you not to put it in your house oven if you are married or don't want the smell in it. I don't know if it would harm you, but it does have an odor. You must blast and degrease it thoroughly for it to look good and hold up. If you happen to have newly anodized/parked parts that have enough "tooth" for it to hold, you may be alright. If there is anything over the anodizing, it will not stick. I always degrease, blast, and gas out. |

We apply a lot of CeraKote. "H" series is the bake on finish and "C" series is the air dry formula. "H" series has a higher wear, chemical, and abrasion resistance while the "C" series has a high temp rating.
Meticulous prep is the key for a long lasting good looking finish with any finish. Clean, re clean, and re clean again. Then blast with an abrasive media (alum oxide or granet) in 80 to 120 grit @ 60 - 80 psi. If you use beads or sand they will leave dimples in the substrate instead of scratches and the coating will not have enough to bite on which means you wont get the durability you want. Yes, we coat receivers inside and out. You can coat the gas tube but I would suggest using the "C" series due to the heat that it could see . We get quite a bit of stuff other shops and DIY people have done. The most common mistakes seem to be poor prep which means the coating doesn't adhere correctly or they don't have the air to product ratio correct when applying it. Practice on a piece of scrap until it goes on smooth and even. As mentioned above the "H" series is the most durable but the "C" series has a higher temp rating. You can cure "H" series in your oven. It will have a smell when you cure it. When curing verify your thermostat with a thermometer (most aren't exactly correct). You want to check for hot or cold spots inside the oven. Cure time starts when the part reaches temp not when you shut the oven. We use large convection ovens and check the surface temp of the item being cured. I would also strongly suggest wearing a respirator, spray in a well ventilated area, and wear protective clothing. If you get some on you wash immediately and don't touch your face or other sensitive skin. |
