Deck lid rattles bigtime

I don't know about moisture problems, but that foam expands like crazy. I was helping my brother-in-law install new windows and he shot some great stuff into all of the little crevices around the windows. When the foam expanded it warped the window jambs so much that we couldn't open the windows. We had to pull out the windows and scrape off all of the great stuff.

Beware of expansion problems.
