The Aerospace Protectant 303 is a UV shield that also works very well on these seals. We use it. The latches for these windows are adjustable and sometimes way too tight; I suspect this is also a major factor when they stick, even to the point of some of the seal coming off on the glass. Use the 303, silicon lube also works but not as well.
