Reflectix over the skylight

I would like to have something in the skylight blocking the sun most of the time but don't want to chance damaging the plastic skylight. The instructions warn against closing the shade fully in sunlight because of heat buildup so I went with the outside cover. The two foot wide piece of Reflectix covers near all of the skylight and gets rid of the solar cooker effect so that I can flop down in the bunk in the middle of the day in comfort. I use four tiny binder clips on each side and flip the little handles up against the plastic so that they won't interfere with clearance under the hatch.

It's only a small bit of trouble to put in place and remove, and the best I've been able to come up with so far. I much prefer the metal hatches on my previous campers, but that's the way this one was built.
