I finished putting a clear window into the door of my Big Agnes Fly Creek UL3. I must say that I felt like a "prize idiot" cutting a hole into a key part of the rain fly of a brand-new-never-used tent! But hey, I really wanted to have a window so we can tell if the skies are clearing…
Thanks to all the BPL'ers who responded to my plea for help in choosing/finding the correct material for the window. In the end, I went with a UV-treated 20-guage marine vinyl. (Probably a teeny bit too thick, but I couldn't find any 10-guage in a small piece for a reasonable amount of money.)
I seam sealed with 2 coats of a slurry (1 part clear silicone to 2 parts odorless mineral spirits), and it passed the shower test with flying colors!
