Junkman, you are a piece of work.........
I happen to WHOLE HEARTILY agree with you.
I believe you left out the fact that in MANY area's of the country the car WARSHES (Jk) have to Recycle the water! So then they high pressure the very fine particles of dirt and recycled water, at your paint, like a sandblaster.
Anyone that does not wash their own car, better have a good excuse, like "I live in an apartment and have no hose".
Also, the more you wash the car, the worse your paint will look over time. Best Scenerio........Wash, then drive, then detail spray, then cover, then drive, then detail spray, then cover. (not possible for those with no garage).
I have 13,540 miles on my 07 SKY and only washed the car about 6 or 7 times. I use a very expensive super soft microfiber and good detail spray to LIGHTLY take dust off. I never drive in rain or snow. My paint is like the day I picked her up!
