Hey Azrok,
This is one of my pet peeves about RnB that I wasn't going to bring up, but since you ask me directly I will speak to it. Mind you that this is just my personal opinion based on my experience so far with the 10+ events I have done (including a couple 9+ hour days in kit). I would stick to the CC and 0000 steel wool and avoid the RnB as much as possible. The only place I have RnB on my entire kit is the gauntlets because I purchased them already completed that way. I have found that no matter how old, dry or polished the RnB feels to the touch, it still rubs off my gauntlets and gets on my vest and ammo pouches and it is not exactly easy to get it off leather. I am constantly trying to remind myself not to rest my gauntlets on my ammo pouches, but it is hard not to do it when you get tired.
I have to admit the jury is still out for me on how long the CC will last though. I carry my kit around in the largest Stanley box with foam in the bottom, but the plates are getting pretty scratched up just touching each other in side the box. I considered using cloth or foam to protect them between layers, but I fear that it won't all fit inside the boxt then. I have to carry my helmet seperately as it it right now. I would be very interested in hearing what other people are doing to protect theirs while they travel around between events.
