As stated above, the rubber molding, above, below, and in between the windshields is easy to remove and replace. I strongly suggest you remove it and check for rust. I found surface rust over about 50 percent of the frame and a coupleof places where leaks had started. Treated with rust neutralizer and painted with Rustoleum.
I check it every year and so far no new rust.
There are also two steel tabs that the glass rests on while the adhesive cures. Rust expands ands puts pressure on the glass, causing cracks. I checked with Winnebago engineering and they confirmed that after theadhesive cures, the tabs serve no further purpose. I carefully bent mine down to take pressure off the glass. One was so rusted, it broke off.
