I stuck the wallpaper on a spot where it came off. It was a very difficult spot, near the windshield. Initially, I started with windshield adhesive, but the attempt was a failure. It was too hard and didn't work with the extension nozzle I was using. The pressures increased significantly. I also used the Logo Silic adhesive with an extension nozzle and a small tube because I couldn't access the area near the windshield otherwise. It was a bit difficult for the Logo to come out with a good gun, but eventually, I managed. It is a soft and user-friendly adhesive, as long as it is not old because it dries and hardens gradually. Personally, from where I purchased it, I asked, and an employee was very helpful and told me that their order was recent. Indeed, when I received it, I saw that it was soft. As for the performance of the adhesive, it will be evident over time. God willing, I will come back if there is a problem, and if not, maybe in about six months, I will reassess. I gave it 4 stars because I don't know the long-term development.
