Hey Tony, that's new for me ...... so Safe Restore will affect glass if applied on the tin side ?? No wonder why I had a cloudy spot on a window I cleaned the other day, no problem because 90% of the windows in that house are gonna have to be replaced, so owner was " don't even worry".
If I go back in time even more I can remember a couple of spots on windows where SR was applied, wasn't as bas as last time, looked like run off kinda stains, no color, pretty much blended in with the glass, but if you looked closely you'll notice.
I was thinking in ordering some dehazer (sp?) don't know if that is the product, I've seen that somewhere, it was recommended to "fix" stuff gone wrong with CC550.
