---------------------- multipart/alternative attachment Mike, I have no idea what manufacturers are using these days. I suspect most of these new pianos are poly's of some flavor or another but I don't know if they're water based or not. The reason not to use steel wool before spraying (or brushing) a water based product is that the water will cause the very small particles left behind to rust. They are imbedded in the finish and make removing the finish you just applied the only resolution. Using water when rubbing out the finish is different because the water isn't part of the finish you're applying. Make sense? Easier just to stay away from wool altogether if you can. Just my 2 cents.
