Review: 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!
Review: 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.

## Questions & Answers

**Q: Will this be good for covering a 4 awg wire splice or should i purchase the wider pad instead?**
A: We have used this on #4/0 which has diameter of 0.46 vs. 0.20 for #4 wire size

**Q: PLease for:
1. 150 x Scotch 22 Heavy duty Electrical Tape(25mm x 33M).
2. 150 x Scotch 23 Rubber Splicing Tape (25mm x 9.15M).
Regards
Vijay Kumar**
A: The #22 HD tape is for making common electrical splices/protection. It is "thin" and should not be stretched when applied to finish - always "cut" the tape, then finish the last wrap. This provides OK weather proof, if applied in 2 or more layers, that over-lap each other by 1/2 the width. Whereas:The #23 tape is a much thicker and "rubber" vs a plastic - it is spongy when applied. This tape is called self amalgamating which means it loves to STICK to ITSELF and forms a true moisture barrier when laid on carefully using that 1/2 width overlap. It should be "protected" from the elements by a layer of the #22 plastic tape to finish the splice correctly. It also provides extra voltage protection for high voltage wires - ie, 2 or 3 layers of this should stand up to 2500 to 7000 volt mains service, whereas the #22 tape is only good for up to 600 volt service. Thickness is used for increased voltages.I am a ham radio person, NOT a lic electrictrician so consult a professional if you need more understanding.

**Q: Can I use this to repair wire insulation on my car where I can't use shrink tubing?**
A: You might find this tape bulky for that application.  Temperature to 194F so not all engine locations. I do not know about resistance to fuel and oil.

**Q: Good for garden hose repair?**
A: I've used it on multiple applications with great results but have never to repair a hose.  I'd be curious to see how that goes.  Depends on the leak?

### ⭐⭐⭐⭐⭐ There really is nothing else like this...
*by P***O on July 26, 2025*

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.
