Rainbow Antenna Ball Topper

I put this ball on my car's antenna. Well after a couple months it faded so that you could not tell if it was rainbow colored. It just looked like a bluish colored blob. The worse thing I did (and this was my own fault) - I superglued the ball onto the antenna when I put it on because I thought otherwise it would blow off. Well, I had a surprise when I took the car through the car wash - the car wash tried to grab the whole antenna off my car because the ball was stuck on so tight. Finally the ball came off and left my antenna bent. Anyway, I didn't learn my lesson because I just got another ball and superglued it on. I have given up automatic car washes. :-)
