<html> I am not a refinisher, but have been around polyster for a while. The best way to get a good satin polyester is to use lacquer.  Sounds funny, I guess, but it's true. If you want to create a smooth base coat with polyester, then simply top-coat it with lacquer and rub it out as usual.  The lacquer adheres to un-polished polyester very well. If you have a satin polyester piano which is not practical to top coat, then the best procedure is to do your final 0000 steel wool or fine Scotch-Brite pad rubbing with automotive wax.  This will help darken the final product, but will be somewhat temporary.  It tends to get splotchy after some years, and needs to be redone.
