Hi,

I use "homebrew" on my glass for water spots: 25% vineger, 75% water.
It's not harsh enough to damage the paint if sprayed on, let sit just a
minute or so, and wiped off. Left to sit longer, I can't say. As they
say w/ many products, "Test first in an inconspicuous area."

wouldn't reg window cleaner or even water remove the spots?

I live in a big city and the windows get a coating on them and a
shower or water drops may sit on the glass, and cause a spotting of
the coating that can take 20min of using the wipers to wear it  off,
and can makes seeing in low light and light rain conditions really
tough to see with the spotty haze. One time following a semi I had to
stop, and what took it off was Spitting on the glass. Bug and tar
remover would take a long time to remove it. I recently started trying
Rain X recommended by a friend, and applying a 2nd coat takes the
coating off, and seems to delay the buildup, or it disappears with a
few wiper wipes when it rains.
