During a storm a while back a hail stone cracked the outer "bubble" of my shower skylight. The patch I made seems to be pretty well water tight. I had taken the inner panel down to allow things to dry out and to inspect for leaks. With the major thunderstorms we have had of late, I am now certain there are no leaks and it's time to put the inner panel back up.
Then I had a thought. Since the sunlight coming down through the skylight is so intensely bright and heats up the trailer, too, why not temper it just a bit while we have the skylight apart?
I needed something just laying around, something paid for that I don't have to go get. After some scratching about, I came up with, get this, parchment paper. (Bakers paper)
First I cut a piece to fit the clear opening in the panel. Then I discovered that no kind of tape will stick to parchment paper. I didn't want to use a permanent adhesive either. So I just pulled a large piece off the roll and stuffed the whole thing up in there.
Now the light is not near as bright and is softly diffused. And cost me nothing but some time.
