Thank you for not flaming me and I appreciate your effort to clarify but you speak of only one method of softening water, one which requires equipment. There is also a chemical method using chelating agents which complexes the Calcium Carbonate in the water and prevents its deposition on the surface.
The point is that besides the soaps for cleansing and the wetting agents to lower the surface tension of the water there are also chemicals to soften the water preventing it from beading and allowing it to sheet off the surface.
I think we can both agree that that is a lot of chemistry being sprayed on your paint.
