      Absolutely great stuff. I have it on the outside roof exposed to weather and sunlight and it is great going into the third winter . . . and I use it under carpet instead of vinyl and I can put it down cheaply.

        Product is very good once down. Unfortunately product was difficult to lay by not being able to lay half at a time like other brands. and paper backing sometimes stuck to ice shield. I would choose a different brand next time only because of this.

        Do not know how well it works but putting down is next to impossible. Paper on the backside tears and it is just so sticky. Can't do it by yourself. I have use other s ice seal worked well and I could put it down by myself. Will never use again. It may be great stuff but to labor intense.
