Just a few tips regarding the use of Super Glue Gel.

I buy it at the dollar stores. Three tubes in a foil pack.
I use a 3/8" punch to cut out small patches from an old inner tube.
Place these and the Superglue tube in a small plastic ziploc bag.

When you have a flat, clean the area around the puncture with a little spit and rub it dry.
Apply the superglue to the patch and use the plastic ziploc bag to press the patch to the tube.
The plastic bag will keep the glue from getting on your hands. You want to apply pressure for about 40 seconds.

Cyanoacrylate glue actually bonds very well to rubber. Moisture absorbed in the rubber actually helps to catalyze the glue.
The problem is that it does not stretch very well, so you want to keep the patches small. 3/8" seem to be perfect for
snakebite flats.
