Quality and Fitment
Great for Highlander Hybrid Battery Sealing - Needs Heat! I bought this to seal the frame of my Highlander’s hybrid battery to prevent air leaks, similar to the strong OEM tape. At first, I was disappointed because it didn't seem to stick at all. However, after some research, I learned that this type of tape works best with pressure, stretching, and a bit of heat. I used a hair dryer to warm up both the surface and the tape itself, and then it bonded perfectly. For my specific purpose, it’s a great product. I wanted to share this tip in case anyone else runs into the same issue!

Dang, This Is Sticky! Not A Caulking Tape
Good stuff. But NOT for installation sealing. It's stretchable but not conformable to irregular surfaces! It's only adhesive on one side but it is very aggressive. Once applied it is nearly impossible to remove. Use with caution and forethought! I was using it for the wrong purpose. It is meant to be used as an overlay wrap. Once the two surfaced touch they fuses together instantly.

There really is nothing else like this...
There really is nothing else like this....it's not cheap, but it really works. I tend to use it for bicycle-based applications but for whatever you need, this stuff works. I love how it can stretch and flex but still hold its tension/stickiness when applied. For my uses, one roll lasts me a long time.

Expensive but works well
This stuff works, espescially for wrapping and waterproofing underwater hoses and wiring, but it’s expensive. Needs a competitor product.

Just as good as MTB Ridewrap Chainstay Armour!!
Ridewrap chainstay armour is only a roll of rubber tape that costs twice as much as this product! I would highly recommend this product to protect your mountain bike frame and chain! Learned about this trick from a popular mountain biking channel on YouTube, I think GMBM? Anyways this product is perfect for protecting your mountain bike frame, whether carbon or aluminum!

Good Top Coating for Wiring
Used this to wrap wiring for a protective coating. This tape sticks and seals very well. It is pretty pricey though and do not go very far. It is a very good product without doubt. Will buy again if have a need for it.

Works great for mountain bike frame protection. Just know that it's hard to remove. Take your time when applying it.

Got this excellent black tape for mtb frame protection. I highly recommend 2228, was easy to apply. I used one box (£20) and cut strips and fitted side by side. It is maluble to seal together. Covered underside of all the bike frame, to protect against stone chips. Used on down tube and chain stay. Not bothered about weight of tape. Might be a pain to get off, but I will be putting new on.

Used as slapper tape on my chain stay, sticks well and looks good.

I am sure it is used for other things but I bought it for use on my bicycles. Sticks well and is thick (one sided only). 3M/Scotch quality. Much easier to order from Amazon that to hunt for in the stores...
