Nice fresh tape for sealing leaks.
Very handy for plumbing leaks. I am bad at plumbing repair so always need this, This roll was nice and fresh so it worked well. This kind of take looses effectiveness with age.

Molds to your application and seals to itself.
This self-sealing tape worked perfectly to seal moisture out of exterior wire splices. I purchased a new tractor that had several exterior wire connections and splices that were enclosed in a rubber boots or plastic capsules. they had no gel or sealant to stop them from corroding. I used this tape to seal all of the connections. That was a little over two years ago. The tractor has been out in the rain, covered in mud, and pressure washed numerous times. I've had no wiring problems. My previous tractor (Green) had constant corrosion and wiring problems every time it got wet. To be fair, I believe I would eventually have the same type of problems with my new tractor if I had not taken the time to seal the connections. Finally, I also used this tape on wiring on my excavator. The wires that run through the ROPS to power the lights had rubbed through the insulation and shorted out. I wrapped all the rub points, the new wire, with this tape. So far no problems.

Much better than electrical tape.
This is very useful tape. There is no glue but the tape sticks to itself so well its incredibly hard to separate. The tape stretches well too. This means you can create an incredibly tight coating around electrical connections that are impervious to moisture. Much better and more permanent seals than you can get from any electrical tape and the result looks professional and well done. I don't think this can be overstated because I have many times had the occasion to remove electrical tape from connections because the glue dries out and the tape comes loose.

Excellent Product! Highly recommend!
This is great for coaxial Connections that are outdoors or otherwise in danger of moisture... Works great on all types of Antenna Connections. I highly recommend. This product will dramatically increase the life of not only your connections, but the coax cable as well. Regardless of the Cost, this can be the life of the coax and antenna connection. Seems to be of good quality. I have used this in Avionics (Aircraft Electronics) for decades and now it is available to the public... All Hams should have it as well as anyone with outdoor TV Antennas. This is the best value for money for the longevity of your coax that is out doors or otherwise in danger of moisture damage. It is very stretchable. You pretty much have to cut it off, because once it is there, it is pretty much sealed. Do not expect to remove and reapply! In regards to removal, you pretty much have to cut it off. This is great stuff for outdoor connections or where there is the possibility of being exposed to electrical (Hot Tubs, Sauna, Jetted Tub (one the wiring)).

Good enough for who is for
Perfect for sealing antennas connectors

Only good for wraps and sealing cord
Similar to engineer tape but not worth it unless you are doing seals or wraps the tape doesn’t adhere to other surfaces besides the tape itself

I used it for what it's not intended for and it was still perfect!
I used it to wrap around the welds on my exhaust because if you know as well as I do it's hard to get those top areas in some some hard to reach places. Used it to cover up an exhaust leak in a very small pinhole. Wrapped it up and let it sit. So far so good. Covered up the hole beautifully
