DuPont FlexWrap EZ 2 3/4" x 15' Flexible Adhesive Flashing Tape

Arrived quickly as ordered. Flexwrap was great, super flexible and super sticky, great for pipe penetrations

This is the best. Way too expensive but when you have difficult joints to seal there is nothing better. Looks like crepe paper. Not great looking for exposed appearance joints, but takes paint well. Very stretchy. I use for wood beams intersecting vertical (angled) joints at lots of weird angles. Can reposition if not right on first try. Clean of all dirt and dust before applying or it wont stick

This is a great product to use. It was effective for flashing penetrations on a new construction home that the sub contractors clearly weren't going to flash (It's not like the siding guys were gonna do it, but oh well).It works well but can be tricky because it's flexibility is lengthwise. It doesn't stretch along it's width. So it took me a little bit to get the hang of how to stretch it around the holes in sheathing. This was cheaper than Zips strategy flashing, but I'd imagine Zips is easier to use because it stretches in all directions
