I have another thread going, "Bleeding Brakes?!". During the thrash to get my brakes working properly, I tore out all the brake lines and re-ran them with Copper-Nickel brake lines. I had never used the stuff before. Bends nice and flairs nice. Kinda hard to keep straight, it is so soft though. Looks real nice. too. My question is what will it look like in a couple of years? Will it turn green? Or a brown like old copper? Could a guy possibly clear coat it before installation? Would that really help preserve it looking nice? Some of you guys must have older copper-nickel installations. What's it look like now?
