    Hopefully someone else will try a Glock slide first.

    Not sure, really

    Nickel phosphorus and nickel born are essentially the same thing. Nickel boron is typically a little harder, but less corrosion resistant. We evaluated the boron stuff early on, and didn't think it did as well with PTFE either.

    DLC is a whole 'nother story. Let's just say, I'm not a fan.
    Care to share why you're not a fan of W DLC?

    Diamond like carbon is a wonderfully wear resistant finish. It is also a very thin, very brittle finish. It does not offer the best corrosion resistance. And most importantly to me, it practically all but prevents future work done to the gun.

    However, if you plan on no further work, like the color, keep the gun in a non corrosive environment, and are horrified by holster wear (99% of the 1911 crowd is) - then this is a great finish.

    Every coating is a compromise. Everythin is a compromise. Picking the right gun/coating/airplane/Le Mans car is all about picking the best compromise.

    Bill,

    Are there any issues with tolerances on bolts and bolt carrier groups? Would you coat just a bolt and cam pin? I have spare bolts and cam pins I'd like to get coated, just wondering about your feelings on this.

    Thanks for any info sir.

    Sure.

    On clearances, if you have something that is fit really tight, a thinner coating can be used easily. Our bath plates out at 0.00025" per hour. So, we can easily adjust the coating thickness.

    But on MilSpec bolts and carriers, the clearances are very generous.

    Bill - could you do a revolver? I've got a Colt Cobra that needs refinishing.

    If it's totally stripped, sure. I just don't want to spend a lot of time pulling apart guns for the price here.

    Great, I'll stay tuned for when you get up and running on aluminum.
