That was going to be my next suggestion either that or plasti-dip. There have been a bunch of really well-done plasti-dipped bikes here in the forums. I've done several parts of my bike black that way. It's super easy and since it is not permanent you can try it to see if you like it or not. I did a couple parts red on mine to see if it would be worth powder coating and decided against it.Have you considered taking the panels to somebody to vinyl wrap?
I was in at my local vinyl wrap place and they were doing a complete wrap of all the panels on a sport bike. Looked awesome.
