XFasten Butyl Sealing Tape, Black, 1/8-In x 3/4-In x 30-Foot Plumbers Putty, RV Sealant, Boat Sealing, EDPM Butyl Tape

This sealant tape actually works great. It is malleable, had great tack, and appears to actually be water tight.One tip: I would suggest a Magic Eraser or similar scrubbing tool to remove any excess residue. It comes off easily that way.

it good. it make plastic stay in place. strong like bull. very good, sir.

Well packaged and works as expected.

Great item and was an easy install. It seems durable and the thickness is what I needed.

I am on my 4th roll of this - restoring a 1962 camper. The good = it works, it arrives on time and it is as promised. However, all 4 rolls have had wildly different adhesion, like they were made in different factories, or with different formulas....but all 4 worked fine. It will definitely stick to itself and your project almost instantly, then to remove it you will stretch it... so be careful and put it where you want it the first time!

Replaced moisture barrier in jeep door. Tape adhered to door great, moisture barrier adhered to tape easily. Very good product !

My husband used this for a roof. It worked as expected.

This stuff is really good -- and comes packaged insanely well like an Apple product. This is a company that understands that butyl tape needs to be protectively packaged, knowing that it sucks when a product comes to the customer's door looking like a chewed wad of gum. Quality of the tapes seems high as well and applied easily and well to my flashing/sealing of roofing components.
