Does wax prevent water spots?

I haven't washed my show car for 2 or 3 years. I carefully dust it off with a California Duster and wipe it down with a spray on detailer and some quality microfiber cloths. This is to avoid a 5 hour car wash and subsequent drying to avoid dreaded water spots. If you leave water spots on a fresh paint job, they may become permanent marks in the paint requiring color sanding and polishing to eliminate them.

When I do wash it, I fill a 3 gallon Hudson sprayer with deionized water and use it for the final rinse. Then hit it with a leaf blower, and wipe it down with spray detailer and the correct cloths. It takes a long time to do it right and not swirl up the finish after spending a lot of time to polish the paint. Between washes, I keep it gently dusted and wiped down.

My black paint looks 3 inches deep, because I spent the time to polish the micro swirls off the paint and take care not to mess up my polish job with careless cleaning, washing and wiping.
