IMPORTANT UPDATES TO REVIEW, CIRCA OCTOBER 8, 2020, AND JULY 7, 2021:OCTOBER 8, 2020 UPDATEWhile my enthusiasm for this product remains unabated, there is a really BIG problem that surfaces with certain rolls and even entire batches of this tape, in my experience across both width sizes that I use, namely, 2" and 4". The problem is a Quality Control (QC) and Quality Assurance (QC) problem, or rather a lack thereof, along with an underlying production problem at the factory.The problem is that some rolls of the tape, when the plastic wrapping is removed from the roll and the roll opened, turn out to be missing the slit in the tan paper backing (aka liner). In most cases, if the first few feet of the roll are missing the slit, then the remainder of the roll is missing the slit as well. In other cases, the first 5 or 10 feet of tape on the roll seem to have the slit, but then, as you go further into the roll, you discover that the slit is entirely missing, or is not sufficiently deep.Of course, the missing slit makes it NEAR-IMPOSSIBLE to use the tape in the real world, for it then becomes very difficult to remove the paper backing/liner from the tape.I first discovered this problem on some 4" wide rolls of this tape a bit over two years ago, but unfortunately, those rolls had been ordered from Amazon over a year earlier, and thus they well past the product return period. The ugly reality of this ongoing issue was again slammed home for me today when Amazon shipped to me four rolls of the 2" wide tape, and upon opening the box, I chose, as I always choose to do with this product nowadays, to exercise extreme due diligence by removing the plastic and paper wrapping from each roll to ensure that the slit in the backing/liner was indeed present. In the case of this recent order that arrived here today, ALL FOUR rolls were completely missing the slit, although the packaging bore the correct 3M part number, namely 8067.The biggest annnoyance about this problem for me is that I have called various 800 toll-free customer service numbers belonging to 3M over the past 2 years to report this issue as a serious manufacturing defect and an ongoing QA/QC failure at least two times, and each time, their response was one of completely refusing to accept responsibility for the problem, as well as a complete refusal to attempt to try to prevent future occurrences of the problem by revising their QA/QC methods or by modifying/upgrading their manufacturing methods.In each case, an obviously bored and apathetic and totally disempowered low-level Customer Service staffer essentially said to me, in effect: "Well, what do you expect? The stuff is manufactured in overseas factories, usually in Asia, and our warehouses have to accept the boxes of rolls shipped to them from the factory on an "as-is" basis. You cannot expect our warehouses to check each roll individually to ensure that it was manufactured properly! That would be way too coastly!"In each case, they refused to elevate my call to supervisors, or to the Engineering department.JULY 7, 2021 UPDATE:My problems with the lack of the backing slit on rolls of the 2" widh tape shipped to me from Amazon continue. I ordered 5 rolls of 8067 tape a week ago from Amazon (Amazon was seller and shipper), and all 5 rolls were totally lacking the backing slit upon arrival. Pending my return of the 5 bad rolls, Amazon went ahead and shipped me 5 new rolls as a replacement shipment for the first shipment (which had contained the defective rolls).That replacement package of 5 rolls arrived here yesterday, and again, all 5 rolls were totally lacking the backing slit, and have also been returned to Amazon!BTW, yes, as other reviewers have pointed out there also exist other problems with the backing paper: it is indeed true that many rolls exhibit delamination of the backing paper, leaving thin layers of tan paper on the tape, which must be removed using a thumbnail, often with great difficulty. Again, this is all evidence of woefully lacking QA and QC on the manufacturing end!In closing, since I have never been able to get any accountability, honesty, or satisfaction by trying to call any of 3M's toll-free phone numbers, this time I have asked 3M, via Twitter, WHY they have not yet fixed the MAJOR QA & QC problems with the backing paper on these rolls of tape, given that so many reviewers have mentioned the problem over the years, and given that angry customers have even called their toll-free phone numbers to complain about such problems. Time will tell if 3M ever responds to me on Twitter with any kind of reasonable answer!- - - -So, bottom line is that I continue to purchase this tape and to use it, but, since I have been burned more than once by finding bad rolls belatedly, I now religiously exercise extreme due diligence upon each order of tape as it arrives, and I partially unwrap each and every roll to inspect it and ensure that the backing/liner slit exists, and that it is sufficiently deep.- - - - - - - - - - - -My original review:This stuff is amazing. I love it! Even though I do not work in the contracting, construction or home repair fields, I use this tape all the time, and I am constantly finding new uses for it, indoors and outdoors!I have bought at least 5 rolls of this tape from Amazon over the past two years simply because I find so many things to use it for, including sealing gaps along seams in walls of sheds, barns, chicken coops, and storage huts, and sealing seams and corners in buildings to prevent drafts and insect infiltration. Believe it or not, that previous list covered only about one-third of the applications that I have found for this tape, and I particularl ylove the split liner, as it makes precise positioning during application very easy.The tape has an incredible adhesive that sticks permanently to almost anything. The tape, that is, the backing, is incredibly flexible, stretchable, tough and durable. In fact, I kinda want to type each of those afore-mentioned qualities in ALL CAPS because they are so notable and so useful.There is no application for which I have tried to employ this tape where it has ever failed to work perfectly, and this includes really odd and strange things such as permanently sealing and repairing a minor crack in the wall of a 5 gallon flexible HDPE jug holding water while the container was full of water and while the small crack was still leaking small amounts of water (in fact, I have used this tape to permanently repair minor leaks in the walls several filled flexible HDPE jugs while they were filled with water and actively leaking. I have also used this tape to seal a fully-exposed seam between two panels in the sloped plywood roof on a shed in my backyard, and it has held up perfectly, despite constant exposure to weather, including sun (although there is some shading from trees), wind, rain, hail, ice and snow.I also have used this tape to seal around holes where non-metallic and metallic electrical conduit passes through concrete walls, even in wet areas, and I have also used it to seal long cracks (due to sun damage from 5+ years of sun exposure) in the flexible clear plastic walls of a hoop-style greenhouse. It works perfectly in all of these applications.I recommend this tape highly. The only limit to what it can be used for is the limits of your imagination.

i am a weekend warrior home improvement guy , i took on replacing my4 doors and 8 windows my self after a bad experience with a "pro installer" who forgot to use flashing can you believe that !!!! my research led me to this 3M product which works amazing and stretches and IT WORKS !! its important to use the roller to make sure its pressed down fully the adhesive is very strong too no leaks or moisture damage or black mold which is the goal

Good tape , very “ sticky “

This the stickies, bestest tape I've ever found.

When replacing windows we tried three types of peel and stick tape3M 8067--very stretchy and harder to cut since it sticks to scissors/knifeTypar Butyl--slightly easier to work with but gets black butyl on toolsPella Butyl from a blue box store--the best, but costs a bit more

I LOVE THIS TAPE! This will stick on wet surfaces where I initially used it to piece together insul board for underneath a hottub. It provides great elasticity which was great when flashing out my windows, it sticks to the siding and 2x4 top rail boards...ps am buying it again because I ran out before I was done with my windows. I even excitedly took this to my neighbor because of it's adherence in the rain! I've used it on my rv and it stopped a leak.

quick shipping and as advertised

We use this on a shed project and it's not really thick but it appears to be very strong it's you have to actually have two people to make sure that when you have it out that it doesn't tape on itself or touch other things because it's pretty sticky... I did find that the getting the paper off was a little bit more difficult than I thought but it wasn't that it didn't want to come off it was just that there was always that one little sliver of paper that kind of went wonky when I tried to pull it off but maybe I was just pulling it the wrong angle....Anyway we did a 36-in door and a window and when I did the door I ran it double thickness underneath just to make sure and I went all the way up and over the door all the way around the window.Overall I think this is a good product I like 3M products I like buying quality because I don't want to have to do it again or fix it because we're going to put lap siding up and it would be really hard to fix.So it does work well and it does stretch.It says it's waterproof and it sticks really well.
