Great product!
Sticks well and doesn't peal. In fact it can be difficult to peel the protective film because of how much it adheres to things. I use a razor blade to help peal it.Also it far cheaper to buy this out of a local hardware store then here on amazon. It's half the price!Amazon is $58.88 right now and homedepot is $27 and the local mom and pops hardware store is $24...

Excellent adhesive. Easy to work with.
Excellent holding power. I will update my review after it goes through a cooling season. But I do not see the moisture affecting it. Great product!
