I know that being able to see light through the gap between roof and window frame isn't a good thing... so before I go ahead and throw some silicone in there I thought I'd ask the list what was the best material they've found for filling this gap?

I bet it's leather but I don't know where to get any. Our hosts show a picture of what looks like sealing material in their parts catalog but unfortunately don't make reference to it.


Cheers.
