I'd get some kind of high temp paint, there's quite a few choices of BBQ or Exhaust paint out there at the home improvement or auto parts stores. Being under a rail scratch durability won't be a concern at least!

Hey y'all, I had to do some contouring on my gas block to get it to clear a handguard (gas block was a cut-down FSB originally done by factory, not me - I had to take the corners in a bit). Anywho, I'm thinking I ought to paint the bare metal. But gas blocks get hot. So do I need to use a special kind of paint, or just some Alumahyde and call it hunky-dory? Any thoughts? Cerakote air cure is a great option too. |

I'd much prefer to use Cerakote (legit gun finish rather than just high temp spray paint), but I don't have airbrush supplies.... You guys don't have a spray can product do you? 
Alternatively, if you don't mind paying shipping, we can spray it for free for you. We do a ton of black for our large accounts and can just toss it in a batch. |

You can use the air cure in a preval sprayer available at most home depots. It won't look perfect, but it'll do the job, especially on a gas block that won't be seen. The only downside is then you'll be out like $50 for the cerakote and the sprayers, which is a bit much for just a gas block.

I looked at the preval spray kits on HD's website. They have the little 9oz one that'd probably be just fine for a gas block - unless there's a reason to go with the large kit (with the spray gun thing). Hell, I'm sure I'll have another use for it in the future. Thanks for the help and thanks for being so cool to deal with. |

wow, that's a very generous offer. That offer convinced me, in fact, that I'd rather buy Cerakote and do it myself than the other possible options available to me.

Just make sure you clean it out VERY well.
The 9oz will be more than adequate. To be honest, the gas block probably only needs a milliliter or two, and the tester sizes direct from NIC industries come in 4oz containers. Figure a hair under 30ml per oz and if you store the cerakote well (Refrigerated), you'll have a backup for some time if you need to spray anything else. Typical shelf life is 6 months, but you can extend that in the fridge. Just make sure you seal the top with electrical tape or something to ensure nothing leaks or kids can't get to it. |

This has piqued my interest and leads me to the question of how many ounces does it typically take to spray an AR with rail and not including the grip or stock?
