duracoat and gunkote = paint.
Cerakote = epoxy ceramic hybrid
Ceramics, bingo, we have a winner.
To be fair, I haven't tested durakote or gunkote, but I've heard enough other makers complain about the results, that I looked for something better. And I believe I've found it.
Call your local hot-rod/speed shops etc and ask who does the
ceramic powder-coating on their hi-perf exhausts and whatnot. (the guy who does my coated blades normally works on racing snowmobile parts.)
That stuff is tough as can be and available in lots of colors, gloss or dead flat. First time I visited my guy's shop, I challenged his coating's durability. He just smiled, handed me a piece he'd just finished and a flat-head screwdriver, and said "Go for it!" I managed to scratch it some, but not much. On finished blades, I've found it leaves a clean crisp line where you grind/polish the final edge, without chipping back. I am extremely confident it will stand up to rough use. You basically have to grind it or re-blast it to get it off the steel.
Very cost-effective, too; unlike the $100 or more I've seen folks asking to do one blade with the "kote" stuff, the small amount he charges me cancels out the time/paper I would normally spend finishing a blade. I don't have to charge my clients extra, it's a free option. It just might take a week longer depending how busy my coating guy is.
I only have to take the blade to 220-300; he
grit-blasts it as part of his surface-prep. It's baked on at 375F, which doesn't harm the temper of the blade. :thumbup:
