What is a good wax for a car?

There are many waxes out there, but they all tend to be the same if they are "off the shelf" brands. Wax causes water to bead up on the car causing lots of water spots over time. Also, all those little beads act like magnifying glasses focusing the sun and eventually can cause pits in the clear coat or paint. Some of the higher end brands are better, but the end result is the same. What I recomend is a product called Car Tech. An acrylic polymer wax free polish for all painted surfaces. It makes your car, boat, and rv resistant to water spots, road tar, bird droppings, salt, bugs ect.
