The problem with polyester and "satinizing" is that the polyester becomes white when sanded. You can experiment with it and see. The appearance is not pleasing as it is in lacquer. I could speculate on why that is, maybe because lacquer is much softer, and sanding/rubbing/wooling on poly doesn't work as well. In the end, if you look at it, it doesn't come out the same. For many years, my job description was doing touchup on new pianos, and we had many instances where I was to rub out packing marks and such on new pianos. As time went on, we began to see the polyester pianos coming in with lacquer sprayed over the polyester finish, especially because it did not look good. Why they didn't just use lacquer all the way was a mystery to me, but whatever. All I can say is, we been there, did that. If you want to try, go for it. You can do it easily, but it won't look like the usual satin black we know. If you like it, more power to 'ya. FWIW. YMMV. Good luck.

Yes, you can rub it out, but it will not look like a Steinway finish. Manufacturers tried this, but it didn't look good. Now they coat the polyester with lacquer and rub that out. It looks much better that way.

Is there any reason why standard rubbing techniques like ultra fine scotchbrites/steel wool/or pumice wouldn't work?
