Great product!

Can you say...wow!?
[This review was collected as part of a promotion.] This has been a lifesaver for me. No joke. I haven't been able to find anything close to this. This has helped me seal off my door and windows that I have been working on. Its the only one that has held up to the environment too. Rain was nothing to it.
We're thrilled to hear that our product has been able to meet your needs and that you are happy with its performance.
Works great
