Review: Good adhesive, stays put, easy to install - Overall summary: - Great adhesive - Easy to install - Good heat protection I needed to replace the 25 year old OEM wrap an electrical harness near a header. First I tried a product that was a roll of heat wrap, but it quickly pulled apart in places where there were turns. I replaced it with this product and I'm very happy with the result. (see the comparison photo) I saw a 1 star review of this product stating the adhesive wasn't very good. It was plenty strong for me, no issues at all. It was very sticky. More on the tape, its similar to aluminum HVAC tape if you've ever used that. If you've never used it before, imagine aluminum foil from the kitchen but one side is sticky. If you mess up and fold it over, you'll probably not recover. Thats just the nature of aluminum tape, not a flaw in the product. Installation tips: - first, measure the length and cut before peeling the backing off the adhesive - then wrap the line you want to protect - finally, peel back small 2"-4" bits of the adhesive backing at a time and seal that section. Then repeat with the next 2"-4" section
Review: Works great and looks nice - Worked great! Easy to install and looks great!
