The tower side of the the CF has alittle red dirt rubbed forever into it. It used to function as a battery tray.
This picture is from an early setup(not current). You can see it on page 30. I cut the wingmount out of it. The other side is clean but has a mar on it from a slip with the dremmel.
Yeah, I hear you Alien and Snoop said on the TRX forum that I should deanodize those aswell as the red tube rods. They have never bothered me. I may do the collars this week, but I'll wait to get the tray to see about the rods. As of right now I still like them red.
