In case anyone is checking this thread looking for ideas, here's where I'm at. I pm'd CSRMarc for some feedback, here's what he told me. Looks like good advice, I think I'll follow it.
Nice job on the wheels, they look great! I know polishing is definately a tough task with a lot of elbow grease and hard work.
But the best thing you can do is just keep them clean as much as you can. Then when you notice them getting to dull for your liking, throw some Mothers or Excites polish on them.
I had an S-10 with wheels I polished and just kept them clean.
Here's why Brandon, any clear you use IF you get it to lay down right without any fisheyes, will peel and flake in a matter of no time.
Reason being is just like with paint, the clear has to have something to grab onto. And since polished wheels are smooth, nothing to grab onto.
I see factory Honda wheels that are machined, which is bare aluminum cut with a lathe, well they are just cleared and I see them all the time peeling, flaking, & corroding from under the clearcoat.
Once this happens, well you can imagine the time stripping, sanding, and polishing again.
The best stuff I've come across is excites polish

Anyway I hope this helps, I know it's probably not what you wanting to hear but IMO is the best route to go.
The only other thing I can think of is to get them powder coated clear. Clear powdercoat with dull the finish though, aswell as if you ever curb a wheel you can again image the headache.
Polished wheels without clears is nice because if you ever do curb check them, just grind, sand, buff & polish. Easy fix.
