My Opinion:

Because of the cost and work involved, I'd choose to just replace the 
cables.
There are very few coax cables and rotator cables that are very 
sensitive to UV.
The only brand name coax sensitive to UV "that I know of" are the 
UltraFlex versions of the LMR series.
I do have "old" rotator cables that the outer jacket is failing after 
nearly 30 years.


If the cables have been up long enough to already show substantial 
deterioration, it's time to replace them anyway.
