Doug,
I talked with Cushcraft before putting up a new A3WS with 30M add-on.
Their suggestion for the center insulator is to spray paint it with
clear Krylon. I did that and also wrapped the insulator with Scotch 88
electrical tape. No UV problem and antenna works FB.
I also refurbished my 15 year old A4S and the center insulator looked
just as you described. I lightly sanded the insulator, painted it with
clear Krylon and also wrapped it with Scotch 88.
While you have the antenna on the ground I suggest taking a peek inside
the traps. The traps for the A4S were full of insect debris. A chore
get apart and clean. I also replaced the sheet metal screws on the
traps with SS ones.
Good luck.
