Sharpening powder coated blades

I've just recently gotten an Izula II, and I really want to keep the coating on the blade. What's my best option for keeping the coating without clogging up my sharpening stone? Should I sand a little bit of coating back from the edge and micro bevel it? or is there a way I can keep the original bevel as close to the original as possible?
 
Shouldn't matter with most sharpening stones. Since most of the sharpening will be done on the already-bare bevels, there shouldn't be enough coating coming off to be a problem. If the stone is lubricated with oil or water or whatever, that'll also minimize what 'sticks' to the stone, and it'll be simpler to clean. With something like a fine white ceramic, you might notice a little more streaking left on the hone. Even then, just keep ceramic hones clean, as you would with any other blade. Ceramics clog more easily anyway, regardless; so, they always need to be kept clean to remain effective on any blade, coated or not.

If you use a strop with compound, you could lay the blade a little lower on the strop; it'll gradually polish away some of the coating above the shoulders of the bevels, over time. Pretty much happens by default anyway, on such strops.

I was noticing on my medium grit ceramic rod (a grey colored one from Lansky) that it was streaking a lot, and when I'd go to pass the blade over the same spot again, there wasn't nearly as much resistance. Like my edge was slipping over the coating that rubbed off instead of grinding along the ceramic itself. I suppose I'll just have to deal with scrubbing my ceramic rods more often

That sounds about right for ceramic rods. If the streaks of coating are clinging to them pretty tenaciously, you might invest in one of the so-called 'rust erasers' to scrub the rods. It's basically just a block of silicon carbide abrasive with a rubbery binder, and it does a pretty good job scrubbing some of the tougher streaks off the ceramic hones. You might also have luck in cleaning them with some Comet/Ajax powdered cleanser, with some water to a paste consistency.
