PAINT THEM. These things cost a mint. Don't know what you paid for them, but I suspect it would be worth it to paint them.
I once had Corbin Bags and eventually sold them. They are great as long as you know what you are getting into and accept it.
1. They are pretty small. Don't expect to be able to carry a lot of gear, and a full helmet will not fit.
2. They are "semi-permanent". While removable, the design does not encourage much on and off switching. I used to only put mine on for road trips, and that worked pretty well, bet what do you do once you reach your hotel on the other end? There are no handles on the bags and the hardware is deep in the bags, blocked by all your gear. Basically, you have to take your gear out and carry it into the hotel with your sox falling and your underwear hanging from your arm.....you get the picture.
3. Security is an issue. They have locks, but they are pretty much crap. Don't leave anything valuable in them for any length of time.
Anyway, they are beautiful, sleek and pretty cool. But they work best if left on all the time and your are not gonna carry a ton of stuff.
