I have located acouple of nice older lenses that are in very good shape, but cou ld benefit from polishing and recoating, I think. Is this a prctical idea (cost), and who can do this work?? Many thanks, Dick

Depends on the cost of the lens. There is a place in Devener (sorry, forgot the name) that will do it for about $125 (one element).
Polishing usually changes the physical characteristics of the element (thickness or shape) and this can materially effect the performance of the lens compared to its' original design specifications. Make sure you ask anyone who does this if and how the element's physical shape is or is not changed by this procedure.
