Steel wool for hard water spots on glass?

kenchan

u should look into water filters..

also dont let water dry and just wipe it while you wash the car in sections. i wash my car in the sun often because i dont have the luxury to chose when i wash the car. i wash a few panels at a time and wipe down with a wafflewave. no water spots.

also make sure to put some sealant on ur glass and paint. i usually spritz Prima Hydro on my glass and paint (safe on seals, plastics, etc) while i dry.
