360Tronics Blue RV Sealant Tape 2 x 16ft, Upgraded Leak Patch Duct Tape Outdoor, Self-Adhesive Waterproof Tape for Roof Crack Leak Repair, Awning Sail, Window Boat Sealing, EPDM Butyl Rubber Roll

This is hardcore. Very large and very sticky. This will no doubt fix a leak. I got this to patch a couple holes in the roof of my chicken coil. So far so good, had a rainy and well and no leaks anymore. A lot for the price, great value with a potentially large use case.

I bought this to use on our duct system. It seals any gaps and is very pliable, making it very easy to use. I would highly recommend this item.

360Tronics Blue Butyl Seal Tape 2 x 16ft works better than I expected. Tape is very sticky, so when applying please make sure you will apply it once - if you attempt to remove it and reapply, it WILL be difficult.

An excellent product, works very well, as described. Super sticky and seals as intended. Good stuff.

This tape is so cool! I didnt know you can even get anything like this. I had a leak on a metal roof and put this on and it stopped it! It is definitely water proof because no water had made it in where I put it. I would definitely use this again should the need arise.

So this thing showed up - and the box felt like in contained a dying sun! HEAVY does not even begin to describe the weight of a complete roll of this stuff!

Worked great to tape my dryer exhaust hose.

Ive never used these types of tapes before but it was not as easy as I thought. It was much stickier than I expected. However, it works very well once applied. I tested it out on a sprinkler that had a small opening on its side. I taped it up with this and put it back in use a few hours later. The leak was gone and hasnt come back. Looks like the seal has remained the exact same after a couple days also.

Wow, this is awesome tape for fixing stuff in an emergency. This is excellent tape for all sorts of repairs. Its very high quality and heavy duty thick tape that will last a good long time.

This tape is much more heavy-duty than I have ever used. Its also very sticky. I believe it will work OK for certain uses.
