I have noticed since washing my 93 that there are quite a few water spots after I'm finished waxing. I have really hard water in my area, but bought a water filter for my hose, which helps a lot. I usually dry my car outside, which could be my problem, so I tried drying it in the garage this time, and did notice an improvement, but there are still some spots. So I went to Auto Zone, and the guy there recommended that I buy an electric buffer, however I am hesitant to go that route beacuse I have heard that when buffing it is possible to cause paint damage and to have permanent swirl marks. I was curious what you guys thought and if you have any tricks to get water spots out before I go the buffing route. Thanks!
