I have used a product called Adams. they have waxes polishing compounds clay bars, litteraly everything you could ever need. I personally know a distributor of the product. i have been around cars my entire life and this is by far the best product i have ever used. everyone i know uses it they all LOVE it. its worth a try. it goes on smooth and comes off even smoother. You can get the wax from most snap-on tools dealers. or on-line @
