1) Are the keypins in good condition (i.e. no rust, pitting, or 
scratches from inappropriate usage of key spacing tools)? Polish & lube 
won't compensate for these conditions.
2) Remove wippens of some of the most sticky keys. The wippen flange, 
and possibly the jack flange, may have too much resistance. If so, it's 
time to take the action back to the shop and repin all possible offenders.
3) The brand new key bushing job. If the cloth is too deep in the 
mortise, no amount of key easing will get you out of the rough. Check 
them all, and any that are too deep, bring back to the shop and rebush.
And other aspects may be the culprit as well!
Good luck!
