watch the vid at 5:40 you see the pipe move and the rust stay still its fake

It's only like 11 bucks, hell give it a shot and let us know. I know plenty of us have probably wasted more money then that.

For rust and normal cleanup , you can try Chrome wheel cleaners like sold at Oriellys (acid ,be carefull) re the blueing its a natural occurance of heat and chrome , somtimes aggravated by fuel mixture issues , once blued it will not 100% disappear , this like "blueaway" will clean it a bit , The exauast heat causes the nickel in the chrome to revert back to it's pre-chrome state.It's is basically the molecular structure acting in reverse.Chrome goes through many stages of plating,sliver,cadmium,nickel,chrome.Nic… blue it is raw form.Very fine steel wool works best IMO  Good Luck with your new boat Tom
