I fixed the wheel/leaking air issue on both my cars.
I posted a writeup on the repair a while back.
The work entailed:
1. removing tire and valve stem
2. wire brushing the wheel insides, and a good cleaning of the valve stem
area - scrape out all the chalky crap.
3. Apply spray aluminum etching primer (auto body shop supplies) - making
sure you cover the valve stem area
4. Apply regular primer or stove paint - I think I used stove paint enamel
or such thing. I guess anything will do.
5. I think I diluted the paint and applied it with a small brush in the
valve step area . . .several coats.

Havent had any leaks now for several years.
