Why the late 70’s? I don’t think I’ve run into many things I couldn’t scrape from the 80’s besides doors…
Hi Melody,
Only going by material I have read on the issue.
Yes, every one of the 6 new Marvin Infinity replacement windows are smeared all over. Not a silicone problem, but looks like smearing when the grill was attached. Almost impossible to clean. My professional service just left and they couldn’t handle it. And after it rains I have water spots which they can’t remove. I have 50+ years old windows on other windows and they do not have water spots. What is wrong with the glass?
