It took some glue to attach the leather upholstery to one of my chairs. It certainly helped. Here is my review after using one of the gel bottles. Pros: + Easy to use + Dries fairly quickly, skin sticks together in less than 1 minute + Pure color + Comes with 4 areas of improvement: - Gel constantly oozes, sometimes uncontrollably, after you break the seal. If you're not careful, this can leave unwanted glue on your hands or surfaces. Even after wiping off excess glue, it will continue to flow out even if you don't touch it. Conclusion: The product works as advertised and I give it 4 stars because it serves its purpose. One star off because of the extra time I spent mopping up excess glue that leaked out of the gasket. If my review was helpful to you, let me know!
