It definitely turns green on a car that sees regular duty. I still use it for everything though. So much easier to work with over normal steel line and way easier than stainless. I'm going to try painting the lines I put on the Scout.
Today I ordered me some of that Copper-nickel line. Can't wait to install it. It's the only thing keeping me from firing up my engine, which I haven't started in 10 years.
