That would work fine but those little kits are wasteful. Go to a farm or hardware store and get a small box of patches and a small screw-top can of glue and you are good for several years. The brand I use is Monkey- something. Most people carry spare tubes. When you have a flat you swap out the tube then fix it in the comfort of your home. I do carry those small patch kits made for bikes as a backup, but I rarely use them. Once you open a tube of glue it will quickly dry up.
