You could send it off and have it Teflon coated or a similar non-blue finish.
Look at these links:
http://www.mrarms.com/ This company will do a Diamondcoat. You can even get it done in a variety of colors.
http://www.blackicecoatings.com/Index.html They do the Black Ice teflon coatings. I think that they can do black, brown and tan/gold colors, and according to their website they can apply the teflon right over the existing blue.
I've seen a gun with the Black Ice, and it is really nice. The rifle I saw it on had it applied to all the parts, and it was really nice. No need for any lube on the rifle at all and it looked really sharp.
