3M Extreme Sealing Tape 4411B, Black, 2 in x 36 yd, 40 mil, 6 rolls per case

I used this tape to seal a spoked motorcycle wheel do that I could use a tubeless tire without using a tube. It worked perfectly. Super sticky and strong stuff!

MUY BUEN PRODUCTO, MUY FINA

This tape keeps three flexible solar panels stuck to the fiberglass roof of my Sportsmobile poptop. Even with slight pressure as the flexible solar panels go over the bolt bumps on the roof, this tape sticks. I have checked after 1000 miles, 2000 miles, and then 3000 miles, and this tape is completely bonded to the solar panels and to my roof. I guess the only downside would be that you would have to use a utility knife to cut the tape around all the edges of each panel (or whatever item you’re sticking to...) in order to take a panel out if you had to for some reason. And that is not a bad thing. This is the real stuff. It completely bonds to whatever you stick it to and to whatever your anchoring that to. In my case, it’s solar panels to a roof. I just stuck this tape around the edges of each panel and then stuck the underside of the exposed table to my roof. It took five minutes to bond, and according to the manufacturer, 24 hours to fully bond. And I can attest, it works- VERY, very well. If you are trying to stick something to the root of your RV or some similar application – this is the stuff you want. @VocalVirgo

This is what it says it is "Extreme Sealing Tape" - It really sticks!!I used it to seal up a motorcycle rim with spokes so I could mount a tubeless tire on it.I cleaned the inside center of the rim and taped over the spokes to keep the air from escaping.I took my time and really pressed the tape down onto the rim to make sure it all stuck good.I also installed a chrome valve stem I got from Amazon.Then I mounted the tubeless tire (actually - a car tire!!) that I also got from Amazon & filled it to the max air pressure.I let it sit overnight before putting the wheel back on and tire pressure was exactly the same the next day.It's been nearly a month and about a thousand miles of riding - and the rim has stayed sealed!! (-:I've also used this tape on another project where I needed some electrical wires to stay in place and it worked perfect for that too.Once you get it all pressed into place on a clean smooth surface - It's gonna stay there and is not going to come off!!

Item works similar to flex seal. Not as messy to remove. But it is very flexible. I used this on a water hose gun. It burst. After I removed and sealed it again, I added a few layers of duct tape on top. It works perfectly.

My customer had a jacuzzi tub installed in his bath, and it was nicely done, but they didn't put enough support along the back wall and faucet end. This is evident when you fill the tub, or stand toward that end at the shower, because a gap opens up between the caulk and the tub, causing a leak and subsequent water damage to the ceiling on the floor below. There was no way to add the support without tearing open the tiled wall, so the flexing wasn't going to stop. This tape was applied right over the grout, with half covering the tub and half covering the adjacent tile wall. It's waterproof, it stretches to conform when there's weight in the tub, and best of all, the translucent color helps it to blend in perfectly with the white tub and tile work. Awesome product, and easy to handle, even when handling a six foot long strip!

I have tried several different 'sealing' tapes to put a temporary fix on an old leaky paint-flaked window that was inserted in a door. Nothing I tried before would hold and so I didn't have too much hope for this 4411N tape.I am pleasantly surprised at the performance of this stuff. I actually didn't even properly clean all the old paint flakes off, but this tape stuck in place for about a month of heavy rains and hot sun.The tape sticks to itself very tenaciously as well as all other surfaces I tried - something to keep in mind when applying. Speaking of application, it can be tricky and requires a bit of practice. However, even with the less than easy application it's well worth the effort.I will buy more of this tape when I need to weather seal anything else.

Had an emergency, where lots of cold air was coming in thru the sides & top of a closed, double hung window. This was just during the first snow storm of 2020-2021.I used this tape to seal where cold air was coming in, from the inside. Window will be fixed/replaced post pandemic. Good thing I had this tape, which I had bought for another application but never got to use it.Note tape is 15 feet long. It saved us from disaster, since the window is in our bedroom.
