Review on PROMOTOR Butyl Sealant Tape: Ultimate Solution for Car Part, Window, Door, and Windshield Installation by Patrick Ross

So many possible uses. I have used it as weather protection around the rear window of my RV shell and around the seam where the shell attaches to the bed. Just place it where you want it, click on it, and you're done. It's malleable and a bit sticky. Works best when it's a bit warm so it's softer. It doesn't harden or harden, but I imagine it won't be as easy/soft to shove into the seams in cold weather. Easy removal too. Had it a few years ago but didn't know what it was called so I had to search a lot of different terms to find it. Now I know this name and will never miss it again!
