What to use on RMR cut to prevent corrosion?

[CWE]

I'm going to send my Glock 19 GEN5 slide to ATEi soon to have an RMR cut done on the slide. I don't really want to pay $90 to have the whole side refinished and was wondering if anyone knew of something cheap I could put on the milled area to prevent rust / corrosion ?


Thanks
Chris

Any oil should be fine. Just go light so it doesn’t seep into places you don’t want it. And make sure you use the sealing plate that comes with the RMR.

Jagerwerks uses "tool black" which is basically a cold blue solution.
I'm not worried at all about corrosion in my dry environment.
If I lived where it might get exposed to salt water i'd probably make it a point to remove the RMR occasionally and lightly oil it, especially after a known sustained exposure.
With a o-ring sealed RMR installed that area should be just fine with cold blue (which is cheap and available in most gun stores).

Are Glock slides stainless steel or carbon steel?

This is the one thing that FrogLube excels at. Get the paste, don't dick with the liquid. Heat with a hair dryer, let cool and wipe it all off.

Eezox is good too.

OK, then cold blue and a coat of MIL-PRF-16173 corrosion preventive: https://www.mil-specproducts.com/Products/TECTYL-846,-CLASS-I

One of the advantages of using ATEi is that they refinish the entire slide, in coating similar to quality OEM offerings.

If I wanted to skip the refinish cost, I'd send to L&M and let him cerakote the cut segment for $20.

For the record, L&M has done 3 Sig slides for me and I've been very happy with their work.

Ditto on this, I have a slide worked on by L&M with the cerakoting. Though I would suggest futureproofing your slide by getting something like the AOS cut.

Johnson's paste wax, Renaissance wax, or any wax with a high percentage of carnauba and no abrasives will work. The goal is to stop oxygen and water from getting to the metal. Ruger recommends the paste wax in the owner's manuals.

thanks for all the replies and ideas.

do any of you have Glocks with RMR cuts that haven't been refinished?

I know I'm being a cheap ass but here is the cost break down:

Jagerwerks - $185
RMR Cut - 125
Sealing Plate - 10
Cerakote - 50

ATEi - $178.50
RMR Cut - 80
Sealing Plate - 8.50
BLK Nitride - 90


I don't really want to refinish the slide but, my concern is that this will be carried daily AIWB and sweat from my body will be against it a lot.

I had Jagerwerks just do their "tool black" on my 19X RMR cut because I like everything about the factory Coyote finish and didn't want it messed with.
No issues even sweating on it AIWB during long range days in 100 degree summer heat.
I have a dual-illuminated RMR, so no sealing plate just the factory rubber o-ring on bottom.
I very lightly rubbed some oil on the cut area before installing the RMR.

The Dillon home brew car lube of lanolin and alcohol is my favorite corrosion preventative.

I'm waiting on my 17.3 slide to come back from Jagerwerks with an installed red dot and full refinish. While I don't mind paying the money for a full refinish, I hesitated to do it because I really liked the slide's well worn finish to begin with. Just an honest looking, well used pistol.

After hemming & hawing for a bit, I finally decided to go with the black Nitride refinish. My logic was that if (in the very unlikely event that) I don't really dig the red dot, I can sell-off the professionally refinished rig more easily than I could without the refinish. Maybe. :)

Cool, unfortunately Jagerwerks doesn't offer the "tool black" any longer. Its either get the whole slide done or they leave it bare.

Im leaning towards having ATEi do the cut for $80 and using a sealing plate (its a Type 1) and just putting some Cold Blue on it and a light layer of oil.

I had Jagerworks cold blue both of mine. I'm in a humid environment. no problems here

Get some CRC 3-36 multi-purpose lubricant & corrosion inhibitor. One of the primary applications is protecting machined surfaces. You can get it by the gallon or smaller spray cans.
