Wow! You guys are really creative! Who would have thought "rivets"!!!
Since our Mylar is almost 98% reflective, it doesn't get hot to the touch -- what gets hot is what it is pointed at/focussed on, which is our black-painted 1.5 inch diameter 10 foot long copper tube. It does have to withstand being outside which means that here is the Mexicali desert it needs to be able to withstand up to 120 degree (or a little bit higher sometimes) weather. But i think that most adhesives will withstand this type of temps.
We had thought about epoxy but were worried that we wouldn't be able to squeege it out smooth enough. As it is, even out soap solution has spots where there are bubbles. Hmmm....
The spray glue sounds the best, but like one poster mentioned, it sets up pretty quick -- maybe we just need to find one that's slow setting.
Have a great morning!
