This weather sealing tape seals cracks in and around doors and windows. My solid wood front door for many years has had two vertical cracks each about two feet long. I’ve tried many times to seal them with all manner of materials — putty, silicone sealant, caulk, you name it — but within months the cracks reopen. I happened on this tape somewhere and bought a roll. Problem solved.
Goes on just like Scotch tape and is pretty much invisible on the door. A heckuva lot easier than the old seal-and-repaint routine. Cheaper and faster, too. What’s not to like?
