Polished copper nickel brake line

We love it at work! I have personally used 528 rolls of it(25 foot rolls) on customers cars and trucks-we use only the S.U.R.&R. brand because it's USA made -it flares well,bends nicely,can be polished easily,doesn't rot when exposed to salt spray.and has thicker walls than the cheaper Chinese crap. I would never put steel on anything ever again-but that's just me. About the only vice it has is that sometimes the steel line fittings corrode inside the hole and cause them to seize to the line which is only an issue on every day driver cars at disassembly time. Hope this helps!
