I used aluminum duct tape from HD to waterproof the edges of the
insulation
on my solar water heater. It didn't really hold up too well.

Was it UV rated?

I misremembered, and meant to say -stainless- duct tape. My bad.

UV can't pass through the aluminum to harm the adhesive. Some of it still
sticks well, some of it has peeled up. I went out earlier this morning to
check it.

The tape seals around aluminized bubble wrap which is the concentrator
reflector when the lids are open and the extra nighttime insulation when
they are closed.
