Snuffy, I don't know if this is any help or not but, with my woodworking background, if a gloss top coat is applied over a satin/matte base coat the results are usually a cloudy finnish. But reverse the applications satin over gloss and the results are great, a deeper richer look.
I did rub-out a finish on a Browning 425 from satin to gloss one time using fine buffing compound and a damp cloth. It took some time and you have to be careful not to cut through the topcoat. You might try looking in a woodworking finish book and see what most finishers use, I think rottenstone or pumice with some kind of oil water mix as the carrier.
