Qbert Posted January 16, 2021 Share Posted January 16, 2021 So I acquired a Glock slide that was milled for an RMR and it was never re-coated. I want to start carrying the G19 with this slide, but am a little concerned about rust under the optic.I don't care about aesthetics for the most part. Can I just spray the raw area with Aluma-Hyde II (or something else you guys recommend)? I'd rather not pay $80 to have my whole slide refinished and wait several weeks as well. I do like doing things right, but if a little spray-and-bake on the affected area will do the trick, I'm all about that. Link to comment Share on other sites More sharing options...
SteelCityShooter Posted January 16, 2021 Share Posted January 16, 2021 (edited) I expect masking the slide around the milled pocket, plugging the threaded holes and rattle-caning it with Rustoleum will work fine. This is not a surface subject to wear or abrasion so great coating durability isn't important. Edited January 16, 2021 by SteelCityShooter Link to comment Share on other sites More sharing options...
TheChewycookie Posted January 16, 2021 Share Posted January 16, 2021 Go get the whole slide re-coated. Below is a photo from the Jagerwerks FB of someone's slide that had corroded. It's not worth it having a decently large surface area of the slide rusting, especially if this is your carry gun. https://www.facebook.com/JagerWerks/photos/3529508403807325 Link to comment Share on other sites More sharing options...
SGT_Schultz Posted January 17, 2021 Share Posted January 17, 2021 Rustoleum will be fine. Link to comment Share on other sites More sharing options...
Qbert Posted January 17, 2021 Author Share Posted January 17, 2021 Jagerwerks has a vested interest in re-coating the slide. They left out a lot of information about that slide. But thanks for sharing that info. Fortunately I live in the driest place in the country and I don't sweat a ton. Link to comment Share on other sites More sharing options...
SGT_Schultz Posted January 17, 2021 Share Posted January 17, 2021 (edited) I still can't wrap my head around the cavalier use of nitriding in this industry. There is absolutely NO WAY IN HELL I would let anyone send any gun part of mine to be nitrided after it left the factory. Mask around the cut, put screws in the threaded holes, degrease everything exposed with acetone, then hit it with any quality rust-resistant paint from your local hardware store. Do it in 3-4 very thin coats, waiting until the previous coat is no longer shiny before hitting it with the next.

Why not? (Obviously I'm not an expert in metal finishes.) Because nitriding is NOT a finish. Its principal purpose isn't to turn steel black or make it more rust resistant. Those are by-products. And not all nitriding heat treatments blacken stainless anyway. Gas and plasma nitriding certainly don't. Nitriding is a heat treatment that changes the metallurgy of the first .010 - .040 (depending on the exact process settings) of the steel. Its main purpose is to create a nitrogen rich, very hard surface layer in the steel (not on it) while leaving the steel below that at its (mostly) original hardness and toughness.

weeniewawa Posted January 19, 2021 Share Posted January 19, 2021 If it is a bare slide I wouldn't think any cerakoter would charge anything over $50 to do it and that is a high estimate. I know I would do those all day long. Graphite black looks just like the factory finish. Link to comment Share on other sites More sharing options...
