Review: This stuff really is the bee's knees - I've used this for about 3 years now. When you have old double-hung windows, this makes excellent stripping where the windows meet in the middle. I put it on the bottom edge of the bottom rail of the top sash (window), point facing up. I also put it along the top of the top sash, and the bottom of the bottom sash. I would use it in the tracks as well, but I've been rebuilding the windows and putting "spring bronze strips" in the tracks. It's a lot more work, but permanent. I also use this V-Flex in the tracks behind and above the top pulley. I let it run long, behind the spring bronze strip, and it seems to work excellently. Lastly, I also use this on old drawers, where wooden drawer-sides slide along wooden rails in the carcass. I got a quart can of "sanding sealer" de-waxed shellac. I paint the bottom of the drawer sides and top of the rails with it, to give this V-Flex a good place to grip. Then apply it flat--don't make it into a V--on both surfaces. It makes them GLIDE. Some are so worn down that the drawer is "low" relative to the hole in the face of the carcass. In this case, I double the layers of V-Flex right at the point where the drawer is almost closed, with the short piece under the full length piece. This allows the drawer to "ride up" a titch and make a better seal/close. The glue on this stuff is quite intense. My most recent batch that I ordered here on desertcart sticks like crazy. The other stuff that I bought at a hardware store here in town must have been a bit older, as it wasn't quite as sticky. But so far, so good! I recommend it all the time to anyone complaining of drafty windows and doors.
Review: Drafts Noise Dirt Bugs - NO more - This stuff is great. It not only keeps out the drafts, but really helps knock down the noise that comes thru a doors with gaps. One wouldn't think a little piece of plastic would help with noise, but it makes a real difference. Also, keeps dirt and bugs from coming in thru those gaps. Very easy to install, and I have some installed that has lasted over 10 years. Seal up that old door!

### ⭐⭐⭐⭐⭐ Draft stopper!
*by B***S on March 18, 2018*

Wasn’t quite sure what to expect this stuff is awesome! Make sure you point the order snide part of the V towards the inside. My windows are about 13 years old now and never been maintained. This helps with the draft coming in. Quite simply/easy to install. One 17’ package got me through 3 1/2 windows. The big box stuff you can get will work if you never want to open your window. This allows window to be opened and closed. Curious to see how it will help in the AZ summers.
