Long story short, the finish on my ~year old sparrow is hot garbage. After a year of light use and only being cleaned once, it's pretty bare. I'm considering bbq paint, but was curious on if there were any other ideas, as I don't want to send it back to the factory.

Maybe?

Any full auto fire? I wish, but nope. Usually on a MKIV or CP33 a mag and letting it cool There’s the grill paint option. There’s Stovebright aerosol stove paint too, it’s heat resistant up to 1000+ IIRC. The catch is, it’ll be rated to whatever temp you’re able to cure it at. If you’re using a household oven that maxes at 500+/- to cure it, that’s all it’ll be rated for. You’ll have more color options than the BBQ grill paint if that matters. Duracoat has some DIY high heat options too IIRC. I used regular Krylon camo on a 22 can when I rattle canned a gun a couple thousand rounds ago. Even with the can getting too hot to touch pretty routinely. It’s held up fine for me. ETA: Most auto parts stores will have high heat paints too marketed as header paint, engine paint, or something along those lines. |

Silencerco did have a couple contaminated batches of black oxide finish on sparrow tubes, so I'm wondering if that might be part of it. I have not soaked it again since, as I've only put another couple hundred rounds through it. Either way, it functions just fine so it's not worth a RMA over. |
| Mine is kind of the same. It is about 10 to 15 years old. I have no idea what i did to the finish. But the can lived in my truck for a while and got wet. The tube developed corrosion all over it. After that i just rattle canned it which worked well enought. Eventually the rattle can wore and i just stripped the paint off. Ended up just leaving it with a worn finish. Call it character. |

Either way, it functions just fine so it's not worth a RMA over. The CLR is what did it. It’s known to attack finishes. The other parts don’t have a finish. I use CLR to clean all my steel rimfire suppressor parts except the outer tube for this reason. |

And yeah, CLR killed your finish. Silencerco will warranty the finish if I want to go that way, but it's incredibly expensive to ship anything hazmat up here to Alaska. I'd have to ship it to Seattle, put on a barge with a freight forwarder, etc. So it would end up around the same cost as having someone cerakote it locally. I'll likely just bbq paint it in the spring, it's not like I'm going to be shooting it much this winter as it's already subzero temps anyhow. |
