Waterproof and stretchy!
I am blown away by this tape. I’ve used bituthene flashings like Vycor in the construction industry for years, and they work well, with some limitations. I needed to seal a waterfall corner in a raised pond with HDPE liner and was absolutely struggling to find a good solution. Supposedly No adhesive works on HDPE and it needs to be heat welded. Well, this stuff sticks incredibly! I was going to use classic bituthene flashing for this, but it is not flexible enough to create a good seal for this outside corner. I discovered this flex tape and I’m sold for life. I cannot believe how thick and flexible it is and how well it sticks throughout the range of movement. I’m confident this seal will hold up for a while. Not so sure about UV damage though…Pretty pricy stuff, but there’s nothing else like it! Amazon was the only place that I could get it, but it arrived far quicker than advertised.

Great stuff!
I used this stretch flashing tape to seal an attic opening that I made for a vent, and this stretch tape does an amazing job at going around multiple corners with a single piece. The adhesion is great! I would recommend it to anyone looking to seal a penetration in a wall. And I believe they rate it to be used to flash some roof penetrations as well.

Great product
Worked great with our zip board installation. Easy to use.

It's thicker than the other zip tape, but does stretch, it is worth it

First Time Use
In the install of an exterior door this product was used over the lead metal pan as the pan was uneven and did not mold well to the uprights. This is a thiner and more conformal sealant and improved the water tight integrity. Relatively easy to stretch and apply.

stop using electrical tape and start using this Magic Tape!
I entitled this review calling it magic tape. It is sticky, stretchy, and waterproof. It has entirely replaced electrical tape in my automotive repair business and farm. Yes it is expensive but it excelsfor you McGivers out there. Just yesterday I used it to tie together a plastic radiator shroud. It is matchless as electrical tape. It is virtually self vulcanizing by virtue of its stretchiness. It is slow to use because it is 3" wide and a bit hard to remove the adherent paper covering but you will put up with this because you will cut just what you need. I still use it in flashing applications when roofing which is what it was designed for. The company should manufacture it in different widths for different applications and perhaps different colors. They are welcome to send me my suggestion fee.

High quality and very sticky.
I bought a roll of this stuff on advice of a friend and am very pleased. It is a strong, heavy, high quality rubber base material that conforms to just about any surface and is so sticky it makes duct tape look like saran wrap.
