Or do you spend all of your time on here. There was a great article in one of the Mustang magazines (50mustangs and fast fords or muscle mustangs and fast fords) about this. The parts are not polished but basically sanded to a SUPER smooth surface to a point they look polished. The parts are put in a machine that has a sandy material in it that spins and turns the parts inside the machine. It goes thru several different stages with smaller and smaller "grit" material until the end when they are mirror smooth. There is a hardening process also.
It does not wear off.
RUB TWO MIRRORS TOGETHER WITH A LUBRICANT BETWEEN THEM AND LET ME KNOW HOW LONG IT TAKES BEFORE THE MIRRORS LOOSE THEIR SMOOTHNESS. See you in a million years.
It reduces friction which in turn yeilds a little horse power gain and makes them stronger and I would believe reduce heat.
You can apply this process to engine parts also.
It is expensive but it is not rediculous. I think it is hilarious that you guys down a product when you do not even know a thing about it. Makes me wonder about the opinions I have recieved from you on previous questions I have asked you.
I am not quoting the article by the way. Just realting from my memory so I may not be 100% accurate. But I do remember reading the article and being impressed.
Go ahead and start flaming me.......
