I have some experience with Duracoat on guns and now knives.
The most important thing while applying it, is to do your prep work very carefully and make sure you rough up the surface no finer than 320 grit. Bead blasting or sand blasting would be best. I use denatured alcohol to degrease before the Duracoat is applied, no need to buy their expensive degreasing agent.
I just did my BK9 in matte black but no pics yet.

here are some tweener scales in an olive/brown mix over truck bed liner for grip. It has warn very well (no wear at all).
