Review on 🔒 DuPont FlexWrap NF: Highly Adhesive Butyl Flashing Tape | 9" x 15' Roll by Orlando Mohr

I first heard about it from some videos on YouTube. Out of stock at my local stores so I ordered it from Revain. The way it works is that it has tiny crimps that allow it to expand and contract. It's amazing how it stretches along the curves and gently compresses in a straight line, eliminating wrinkles! In the first window, I removed the center liner along with one of the edge liners, causing the tape to stretch along one edge. For the next few windows I left both edge liners in place until they were fully ready for gluing, this worked better and eliminated the stretch. Be sure to press it into the corners with a spacer or other straight tool, and use the J-Roller to press it down. This tape is going nowhere!
