3M Hi-Tack 76 Spray Adhesive, Clear, 18.1-Ounce

4 ½ stars. This item is listed in several places on Amazon. Am sure I bought it from another vendor for around $18 that included shipping.1. The right adhesive- After reviewing other spray adhesives, I settled on this one for the fabric headliner in my 1999 Ford Powerstroke, primarily because the 3M application guide recommended it for headliners and fabric. The headliner had separated from its foam backing where it meets the windshield, stretching 24" from the center to both the passenger and driver side A pillars. Only an after market overhead console prevented the headliner from drooping down to the rearview mirror. So I was looking at reattaching the liner where I had as little as 1/16" in all corners to ~3" away from the windshield. There were other 3M sprays with #s above and below the magic 76 at the local big box DIY stores and smaller volume hardware stores, but not this one, so ordered this from Amazon. The only local stores I didn't try were the craft stores.My biggest concern was that some reviews reported that it would eat foam and in fact, it states on the can that it will attack beadboard or Styrofoam. My foam backer board for the headliner was not eaten as was borne out by testing a small spot prior to full blown use. Another concern in using it was that the tip should be 4'-8" from the surface to be sprayed. That turned out to be an almost non-issue as working a little closer was not a problem.Because of the volatile nature of the vapors, I believe that a respirator that can handle organic vapors is an absolute necessity when using this spray. Moreover, I was going to be using it under the worst possible conditions (inside an enclosed vehicle) and was simply not going to take any chances. I ordered the 3M R6211 Low-Maintenance Half-Mask Organic Vapor, P95 Respirator Assembly, Medium for the job and is reviewed separately. I also used safety glasses that had enough room to accommodate my very thin profile readers from costco for some closer-up work.2. Adjustable Spray- directions on the can say to select the desired spray pattern by turning the tip to the desired position. The tip was set to vertical and I would have preferred horizontal, but I couldn't turn the tip away from it's "as received" position. Didn't want to force it, because my luck is that things break when I that, so I left it. Turned out it probably worked better set to vertical.3. Vapors and safety tips- USE A RESPIRATOR AND SAFETY GLASSES/GOGGLES especially if you have to work in a confined space like a vehicle. These vapors are extremely volatile and extremely flammable. The warning on the can states that even static electricity can set them off. They also linger in the work environment. A "flash fire" can ignite the vapors and follow them back to the can. We are in the monsoon season now and with the higher humidity, static is virtually non-existent. At our usual 10% or less humidity here, static is a real pain.After spraying, I felt encumbered by the respirator and made the mistake of removing it to carefully roll the fabric back to its original position when doing the driver side. The vapor instantly invaded my respiratory system and for several hours thereafter, I experienced a raspy voice and was constantly trying to clear my upper bronchial area and throat. I did not repeat that practice on the passenger side. Don't be stupid, use a respirator that can handle organic vapors. Lingering vapors irritated my eyes after a few minutes delay. Leave protective gear ON until you leave the work area.4. Tack Time- 3M states that when using this spray on 1 surface of two to be joined, TT is 1-10 minutes and when sprayed on both surfaces, 1-60 minutes. With the exception of unintentional over spray onto the foam, I generally sprayed just 1 surface (the fabric). I had secured the side of the fabric to be sprayed with pins, overlaying it onto newspaper to protect the overhead headliner. I had enough time to remove the pins (now tacky) and carefully put them in a container I had prepared for that purpose. I also had plenty of time to carefully roll the fabric back into position over it's 24" length using a thin bamboo skewer. The skewer was actually an excellent aid for this project for working in the tight area at the "A" pillar and for rolling the fabric. Tackiness seemed to become more aggressive as I worked.5. Cleanup- Directions on the can say to use turpentine to clean the tip. Also works on some overspray I caused when first testing the tip outside the vehicle. It sprayed farther and wider than I expected. I did this repair in 2 stages and cleaned the tip several times. A small syringe is also useful for forcing the turpentine through the tip. I used a very small 1cc capacity one that our vet gave us to administer medication to a pet. The respirator help my already irritated respiratory system here, too.Conclusion: This spray helped me pull off what was viewed as a most unlikely or potentially mediocre repair, at best. I took 4 days to do both sides, 90% of which was used to mask for overspray, carefully expose, clean and pin back the side of the fabric to be sprayed. I gave this spray 4 ½ stars because I am not sure how long it will keep the headliner from drooping again. But judging from the way it was tacking, I suspect it will hold for quite a while, perhaps years. Longevity will probably be increased by having taken the care to use some duct tape to pick up as much of the old powdery foam from from the fabric as possible. I spent more time on the fabric as the foam board seemed to be showing signs of degradation the more I tried to clean it.Pick the right spray for the job, observe the safety precautions, prepare in advance for cleanup, don't be in a hurry and you should be as happy as I am, especially if you are doing something in a tight space such as a headliner close to the windshield and A pillars!

Has much better stick than regular spray on adhesive.

I used this to glue a heat pad for an RV holding tank back on that was starting to come off. I just cleaned up any road grime, sprayed the pad and tank, waited about 2 min, and then pressed it on. Make sure to wear gloves as this stuff can get a bit sloppy and it is VERY sticky. I put that pad back on about a month ago, and have driven the RV on the highway for about 400 miles since then, and it is holding on just fine. Worked like a charm.

I never knew headliners were this easy

I just use this in order to glue in the headliner at the back of a 2003 Civic. This is the second time I've glued a headliner with it the last time was 10 years ago. In addition to doing the job a bonus is that the stuff will last in storage for 10 years. Some notes and tips: (1) you want to mask things like you're painting, having a roll one foot wide paper is helpful to make sure you're not going to be spraying on to the glass or trim (2) gloves glasses hat respirator; (3) because it slightly dissolves the headliner foam, I found that when I pushed the headliner with my fingers I left finger dents, so instead I used a yogurt container lid with the rand cut off as a presser to apply more even, sliding, pressure. This worked well. (4) one mistake I made while I was still pressing with my fingers was that I got some of the glue on my fingertips and accidentally touched them to the outside of the headliner. The yogurt lid presser helps with this, but you also just have to be very careful about contaminating the right side of the headliner.

Good GlueYou have to work fast with this glue , Binds hard !

The upholstery on the side door of my Mustang GT started peeling off; it got so bad that almost all the fabric hung down over the car door handle!I tried a few other spray adhesives but none of them held for long. But this 3M 76 was perfect for the job. The side of the door looks like new and it is holding fine in this GA heat!I highly recommend this product for car upholstery applications. Doing this job myself probably saved me a few hundred bucks!
