I am a costume and prop fabricator. The Shoe Glue claims it works on rubber. I attached a Urethane Rubber piece to a fabric costume and followed the instructions exactly. 24 hours later, the rubber piece pealed off. Not only that, the glue did not even bond to the fabric.<br /><br />I even used this the way you should, on a shoe. My brother's sole started coming off so, I followed the instructions. This time I put what seemed an excessive amount of glue on the 2 pieces and pressed them together. This time it worked, HOWEVER. A few weeks later, the shoe started coming apart again. I even used it to bond vinyl to plastic. It lasted 1 week. Did I get a bad batch? Maybe. Did they change the formula? If they did, they should not be selling it. Costumers and consumers beware.
