Glock slide milled for RMR left in the raw. Aluma-hyde?

[Jack Dupp]

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.

If aesthetics are not the concern yeah then just about anything will work. Even cold blue as it is not a high movement/wear area.

IMO the machined section needs to be finished with something to prevent rust.
Agreed that cold blue is an easy choice. Cerakote works too.
I too don't see the need to refinish the entire slide.
