The formula has changed over the decades, but this is still my favorite glue for patching tubes. In the Southwestern USA we are plagued with strong woody "Goathead" seed pod thorns which can easily puncture tires. If you choose not to use a tire sealant inside your tubes you quickly become expert in puncture repairs. The Rema sealant and patches have never let me down - unlike self-adhesive patches which are often claimed to be only a temporary repair solution. The 10 gram tubes are large enough to be practical and will last for many patches, but are small enough to not risk premature drying out of the contents.
