of the Mylar is stuck on, the left half is flapping.
I have done the right hand sunbox reflector, the one that has the thermal sensor in. I noticed a week ago that the temperature inside got up to nearly 60ºC, and the only change had been the Mylar put on the inside mirror position. So I look forward to the next sunny day to see if the external mirror has an effect. If we have a windy day, I am willing to be philosophical if I see the Mylar hanging by a thread in the wind. It is only held on with patches of duct tape, not a continuous strip. That may be a mistake, but it was getting dark and I don't enjoy being up the top of the ladder.
