I think a patch works much better then just glue. Use Vynabond for the glue and a piece of an old air bag or other vinyl. Also look for Thermarest patch kit, they work great too.
I've used Aquaseal on small holes and wear spots with great success. I don't think I'd rely on it for big holes, significant rips or problems at the seams though.
i had to repair some air bags last summer. on the holes (pinholes), i used aqua seal with an air bag material patch. on the seam leaks i just used aqua seal. they all seem to be holding well.
Auquaseal or Seamgrip. As for the patch, any material will do. It doesn't have to be vinyl or airbag material. You could probably use burlap. The sealant does the work, and will make any material you choose airtight.
