Oh yuck, I didn't even think about that.

Oh well, the Statue of Liberty hasn't rusted any, she kinda looks good in green, and the bends and flares should be easier.

How long does it take them to turn green? I have never had NiCopp lines do that.

Make sure when you cut the copper line use a chamfer the end of the line before the flare. It takes a year or so to turn green

My NiCopp brake lines and fuel line haven't turned Green either, and they have been installed in the Panel Truck since 2015.

I've never had it turn green. I'm just was looking at a car I did back in 2010 and the is was no sign of it turning green.

Right or wrong I ran 3/16" lines in place of 1/4" on my truck. I used the nickel/copper lines and it was the easiest brake line I've ever worked with. Flared with little effort and bent easily with no tools.
