Review: A great product - I have never had to use this type of tape before, but we're doing DIY repairs on our refrigerator/freezer. I had no idea what the difference was, if heavy duty was better than regular, etc.., when I was trying to figure out which one to buy. Finally, I decided that the heavy duty tape would be best, and chose this product. I was opening the clear plastic around it and found out quickly that the sides of the roll are very sticky, but I kept the clear plastic and anytime it's not being used I use it to wrap it up. It also has a paper-like backing on the tape. It's a little difficult to get the backing separated from the tape, mostly cause there's no edge to get in between them, but once you get it a little bit apart, they very easily come apart. Those are the only 2 things that I had any difficulty with, but it wasn't bad ~ just a bit frustrating. Overall, the tape itself is very sturdy, easy to use, has a great seal/adhesive quality, it's waterproof, heatproof (to a certain degree), and was perfect for the repairs we were doing. I worried that it would be wasted due to the size of the roll, but it can be used for many different things. It was shipped/received very quickly and without damage. I would definitely recommend this product and seller.
Review: Waterproof and Holds - This tape works on everything. We used it to seal around a window ac. It held up all summer through the heat and rain. It most definitely is waterproof and has a strong hold. We had no leaks or any bees or stink bugs to get in through the area. It did not leave a sticky residue either. Great product! This is our 3rd purchase.

Tough stuff and sticks great. Easy to roll out and great for sealing up a seam between my eaves and rain gutter. Looks like it should last as long as I do. Good buy.
