My house was built at the same time by the same builders as 2 of my neighbors, both of them have the same type double pane windows as I do and they both have major problems with the windows leaking, fogging and etching the glass. I, fortunately only have one such bad window, and would like to try to prevent or prolong the inevitable fogging/etching by maybe somehow treating the rubber seals or something like to this affect.
My thinking is: The seals are rubber. As rubber dries or hardens in the sun, it loses its flexibility and thus its sealing ability. Perhaps I can re-nourish the rubber so that it can maintain its flexibility. Perhaps there is some substance out there that I don't know of that I can drissle or apply to the rubber seals that would recondition them.
Nice idea, or optimisitc fantasy?
Thanks! Hank
