Review: It really works great - Not easy to use and take paper backing off alone It was a 2 person job but the wind was blowing and I was doing it outside We have had high winds and my ripped up tarp has held amazing the horses are not pulling it off line they did the duck tape this stuff is amazing I think it’s the ability to flex that really does the job Totally impressed
Review: Flex Tape 8 inch - I bought a roll of Flex Tape 8 inches wide. It is thick, strong and easy to work with. You peel off the cellophane backing to expose the sticky side when you are ready to use it. It’s way thicker than duct tape, stronger and super sticky. Make sure you get it on exactly where you want it. It’s hard to get it off if you don’t have it line up. You can move it , but pull it up slowly and a little at a time. I like the idea it comes in colors too. Mine is white. I highly recommend this tape. I’m curious as too how long it holds up to the elements. But right now it looks great. One roll is 5 ft , so for bigger jobs, measure first and buy the appropriate amount of rolls. Great stuff. !!
