Bill, thanks for the reply. We're not a big fan of these windows, and really want to change them out for nicer ones. The windows we like are $3-400 each, and quite a bit different than the ones we have now. We really wouldn't be able to just do a few; the house would look goofy unless we did them all. That's not in the cards untill we do the roof, and until wifey is done school and working again.

This window "defogging" seems like a sensible interem step. I just want to make sure I'm not getting hosed before proceeding. Thought maybe someone had experience with it.
