I had a serious leak in my cab over window. Heavy rain and the water poured in. I final broke down and resealed the window based on this video.
I purchased the kit from Seal-Tite website and reinstalled the window. Once the window was out it was obvious where the leak was - cheap foam core.
No leaks now and I have enough left over to do every window on my 24F. It was a straight forward task - Mark Polk makes it look easy...and it was. Took me about 2 hours and 2 beers.
