Aluminum wheels - slow air leaks

My wheels are getting long in the tooth(88 5kq) and I've got a slow leak in
one wheel.
The tire is ok. I suspect aluminum corrosion on the inside of the wheel at
the bead area.

Anybody got some fixes for this?

I thought of removing the tire and wire brushing the wheel insides. Then a
fine sanding followed by an aluminum primer. Afterward, paint the inside
with something to seal and protect the aluminum from corrosion.
Maybe just a fine polish and wax job on the inside?

Anyone got any ideas on this?  My tire guy says this is a common problem on
aluminum wheels.
