Keith,
I don't know whether to laugh or cry. Your story is so pitiful that I 
feel you really deserve some sympathy. Not that free sympathy is worth 
much. But, it got me to thinking about your tribulation and that might 
be of some use.

Just for the sake of discussion, consider this. Maybe the problem is not 
the UV. Suppose it's some kind of contamination. Is there any chance a 
silicone has been used in those locations in the past? Or, for that 
matter some other chemical? I really don't have any clear idea what it 
might be, but since your symptoms are so variable it makes a fellow 
wonder about chemical contamination.

Sympathetically,

Mike
