Review on 🔁 M D Building Products 71548 Interchangeable by Michael Moonin

Used to seal the gap between a window and a portable AC fan (or whatever it's called). When you use it for the first time, it can be difficult to use because it behaves like clay. My advice is to place it in the gap you want to seal and then use your fingertips to gently press down on the edges of the sealant to ensure it adheres securely to the wall or window. . Don't mash everything at once, just the edges. Anyway, I've been using it well on my box for 3 months and the removal process was easy!
