I use Meguiars cleaner/wax a couple times a year on my car, truck and Jeep, as well as on my RV and boat.

In between those waxes, I use a product called Wash Wax All - just spray it on after washing, and wipe dry. I sometimes even use this on my windows. This product applies a fine coat of wax, removes some dirt, as well as any and all wet spots, and in my opinion is one of the slickest and best products on the market. It definetly makes washing a lot easier, and I do get my vehicles plenty dirty driving them off road every day in Montana from May to October. I believe it is used extensively in the aerospace industry, and I buy it at our local airport supply store for about $18 a gallon - which lasts me about 2 years.
