Butyl Tape Gray 50ft 3/4 Inch Gray 43237-34911

i order a roll of this stuff like once every couple months for work i am a telephone and internet tech and we used to be able to order similar stuff called air seal we used it to seal the grommets where the wires come through in the telephone NID box on the house but we cant any more we only get silicone which sucks to use because it doesnt stay pliable so when you add another line in the future you have to peel it out and put new silicone, this stuff doesnt harden it stays nice and pliable and seals the wires up great keeps bugs out and moisture and you get way more for cheaper than the other stuff ive ordered similar to this

This is the 3rd type of tape I have used on a project camp trailer. I first used the light grey putty tape that has the super crinkly paper, then the XFasten white butyl tape, then this GSSI butyl tape. The GSSI is definitely the easiest to use. The wax paper is thick and slick. The Xfasten was good butyl, but in unrolling it the wax paper kept sticking to the butyl and tearing, and my fingers got all sticky trying to pick the paper out. The GSSI paper never tore, and the butyl came off nicely. The trick was to unroll one layer of paper off so that the butyl is exposed all around the roll then start unrolling the butyl and tape together. You have to hold the roll carefully and not let it touch anything (a second set of hands would have been helpful, but not absolutely necessary), but that way the putty stays stuck to the wax paper until you want to peel it off. It cut nicely with a razor knife. I ended up buying a 2nd roll of it, and will buy the GSSI again if I need more.

Works as it should

If you're putting on a metal roof then this is what you want. It is sticky as heck so just realize that once you get a sheet in place and drop it on it's neighbor it ain't going to move. I also used some butyl caulk during my project but this is the stuff you want. Definitely recommend.

got this sealant tape, in a perfect condition box, with plenty of padding. BUT the stuff was terribly squished. I still managed to use it, but had to spend extra time cutting and splicing pieces to bypass the squished pieces. Good stuff, just inconvieniant.
