Only tool is something to cut calk (scissors) easy to install, quick and very pleasant to the eye. A hair dryer comes in handy to assure good adhesion.

This caulk tape is flexible and sticks great. Got this for my resin countertop job and beadboard wallpaper backsplash joint in my kitchen.

Product performance is inadequate to the tasks at-hand. A waste of my life trying to install this. It is not flexible enough.

The material is pliable enough to push back together even if it breaks or gets mangled. It is easy to remove wthout taking pain off the window. It's also removable and reusable.

It was stretched out in places. The so called cords were mashed together so badly that there is no way to use them. I'm horrible at caulking around objects and trim.
