## Description

Product description

Review: Thick, clear, sticks well! - Very thick, very clear, very sticky. I don't understand how some reviews said it was thin. Be careful when you open it... I took off the colorful outer layer, but then also took off a layer of clear film, which is actually the film protecting the stickiness. I wasted about a foot. Seems like a good deal for how much you get! I used this to repair a lawn furniture cover and plan to use it on some cracked vinyl boat cushions.
Review: This stuff is sticky! Like mouse trap sticky - I bought this to patch a split in my in ground pool liner. The liner is 11 years old and will be replaced when I open the pool next spring, but I didn't want water to get behind it. I bought this very heavy clear waterproof tape to keep the split from spreading further. When I opened the package, the edges of the tape felt like mouse trap glue - it was that sticky. The tape is very heavy vinyl (I ordered clear), with a peel off clear plastic film over the adhesive side. It was very easy for me to unroll some and cut it to the correct length, peel off the plastic film, and apply it over the split in the pool wall. The tape sticks very well and you can't even see it. Time will tell if it yellows, but it should get me through the winter. If it holds up well enough, I may be able to delay replacing the liner for a year! Good stuff!

## Features

- STOPS LEAKS BEFORE THEY SPREAD: A pool liner split or cracked gutter will keep getting worse. Apply to a dry surface, press firmly, and the seal holds permanently even when submerged. Repairs pool liners, hoses, inflatables, and gutters in minutes.
- BONDS TO ALMOST ANY SURFACE: Extra strong adhesive grips vinyl, plastic, rubber, wood, fiberglass, tile, glass, ceramic, plaster, concrete, metal, and more. Sticks on dry, wet, and rough surfaces where standard tapes peel away.
- MARINE GRADE WHERE THIN TAPES FAIL: Cheap waterproof tapes use thin adhesive layers that lift in heat and UV. Built to marine standards with thick rubberized vinyl that flexes, conforms, and holds permanently without cracking or peeling.
- EMERGENCY REPAIRS THAT HOLD: Covers cracked car windows, burst hoses, ripped awnings, and broken skylights until permanent repairs are made. Holds through rain, heat, and pressure. Extra wide 4 inch roll covers large repairs in fewer strips.
- CLEAR TAPE FOR INVISIBLE REPAIRS: Leaves no visible patch on glass, vinyl, and transparent surfaces. Apply dry then submerge for pool liner repairs. Two layers of film to remove before applying. Better Boat, family owned, Miami Beach, Florida.

### ⭐ Not good for above ground pool liner repairs
*by D***O on January 21, 2022*

Like many of you who buy this tape, you’re looking at a less expensive alternative to other manufacturers (FlexTape and Gorilla Tape, et al). That’s why I purchased this tape. You get twice the amount of tape for the same price as those other two. Well, after giving it a try I can tell you that it just isn’t good enough. I have continuous problems with my above-ground pool liner. It’s always my fault as I am too aggressive with cleaning and I cut or puncture the liner. In the past, I just used FlexSeal, FlexTape or Gorilla Tape to make the repairs….and they worked well. When I ran out of those, I bought this tape because it seemed much less expensive…almost 60% less. Well, I gave it a try, applying it just like I did with the other brands, and it failed miserably. It didn’t adhere to the pool liner. As a matter of fact, it peeled up almost immediately. I went ahead and ordered the tried-and-true good stuff and will stick with that (pun intended) from now on. Too bad as I really wanted this to work.
