in my area i have horrible water. Everytime i wash my car i always get water spots no matter how fast i dry it. I tried mr.clean auto dry spot free but that was junk. Some one at one of the cars shows told me to get a water softner for my house to get rid of the hard water. Has anyone tried it? The guy told me he got the water softner from Http://www.apswater.com/shopaff.asp?affid=15. Let me know what you think i might stop by there just because it is local.
