[VintageLambo] Window Glass Question

Hi Group, I have a question about side windows. My 400 has some pretty ugly abrasions on the passenger side window caused by the weather strip. The weather strip is constructed of formed sheet steel, rubberized, and covered on one side with felt. Over time, the steel rusts, the felt degrades, and the window ends up with surface scratches from raising and lowering the glass. So my question is this: Has anybody ever found a way to remove the surface damage by polishing? I have seen the ads in J.C. Whitney for a glass polishing kit but that has an aroma of snake oil. I was thinking about a professional service it such exists. I would appreciate any inputs on this because replacing the glass is not an option. I gave up trying to find new glass a long time ago - It is nowhere to be had. Thanks, Jack Who is driving the 400 to work tomorrow.
