    I obviously can't recommend you do that. However, the cut surfaces can be painted over with some simple prep work with sandpaper. The original coating can be painted over top of. We have several dealers color coating using cerkote with excellent results. Our coating is actually a very good base for paint.

    Bake the part at 300F for a half hour after cutting, let cool until it can be handled, then degrease with acetone. The prebake will help ensure the cut areas at the edge of the original finish will be sealed best.

    To degrease, soak for 3-5 minutes and then air dry. Then apply the paint per the manufacturers recommendations. Lighter colors will require more coats for uniform appearance. Or you can apply a basecoat of black on the cut edges and then paint with the final color for best results. The thinner the added the color costs the better, thick paint will make pic rail and keymod accessories difficult to fit.

    Will soaking the cut rail in degreaser affect the factory black coating?

    No, but the cut edges might lift slightly thus the pre-bake suggestion. Doing it after the cut and prior to degreasing will help ensure that any slightly lifted edges from the cutting don't cause any ugly spots or other drama.

    The dealers painting our parts are using this same method with excellent results.

    Any thoughts about different coatings? I was interested in just touching things up, so I'd rather not sand the whole finish.

    Thoughts if bake on cerakote or molycoat would stick to the KMR finish without sanding the whole thing?

    Thanks,

    Man. I'd just tape off the outer surface right up to that cut and rattle can it black. I've done cut down carry handles and spray paint holds up just fine.

    So If I understand this correctly you do not recommend blasting the KMR when using Cerakote. Will blasting the part to prep cause problems?

    Correct. Just degrease and paint right over it. It will stick very well, no blast needed.

    No need to sand the whole thing. Just degreaee and paint as you desire. Touch up the cut area or paint over the whole thing, doesn't matter.
