  Unless I'm missing something I don't believe this UV technique is going to
work on the cloudy rear element of the OM 65-200 zoom. IIRC the UV technique
was touted as a fix for the lens element yellowing that occurred in the
early fast primes that were coated with a rare earth element. The rear
element fogging of the 65-200 is a different beast.
