Update 6months

While in Las Vegas NV temps were geting over110°f and the plastic relaxed Slightly about 1/4" so I used some "light"tan hammer tone plastic compatible rattle can paint. Painted over the wight duct tape burn hole patches. Figured it would help as sunscreen spf 100. Maby. However much ro my dismay it turned out a dark copper. So during my 2nd trip to LV the heat sag was much larger problem @ about 117°f it would sag about .5" on the 2 center spans at the hottest part of the day. But the plastics would go back to tight after about 1-5min of driving got back to the soggy cool NWand it was back to a snear drum.
