... I live near two major freeways (about 1/2 mile from my home), so I just take a 70 mph blast after rinsing my car. Then, I either let the rest drip dry or I use microfiber cloth. And, I always run over the car with "The Glosser" to remove water spots and keep the paint shiny.

In the summer, I will often just use my Mr. Clean car wash kit and let the car drip dry. It works good, but I am not sold on the soap that comes with it. The soap can "gel" in the device, which then deposits itself on to your finish. This happened twice. At first, I thought it was sap, but I noticed that it was water soluble and happens only if I use the Mr. Clean soap. Use a spot-free rinse feature on the car wash kit, plus a bucket of Armor All, Meguir's, or other suds (with a mitt), and you'll be in good shape.
