Bumper shining

Here in Michigan it was called "shagging". The bumper shining question... unfortunately, an SOS pad may have done more harm than good. They are not fine steel wool and may have scratched it more than helped it. They are for scouring and not polishing. You should be using "OOO" steel wool if you plan on polishing anything. I would suggest getting a good chrome polish such as Wenol or the like and doing your best with what you have. Yes, the 70's chrome is not very thick, and once it starts peppering and spidering, you're pretty much out of luck!!!
