It's not the wax that's doing it, it's just UV exposure. It's unavoidable. You can remove it by unscrewing the nut at the top, the one with 3 grooves in it. I tried Back to Black and a few other products, they all had varying degrees of success, but none of them really looked good. I was going to paint it, plasti-dip would probably be an even better option, but I ended up getting a new antenna base. I got it through the parts department at the local dealer, it cost around $6.
