Depends on what you're sealing. OP sounded like he was trying to plug a water leak between hull and tube. Caulk (a good marine polysulfide caulk, like LifeCaulk) would be a better choice for that than AquaSeal. Especially if it's a vertical application, as you'd have trouble keeping the adhesive from running off the repair area.
I keep a tube onboard with the Cotol kicker to speed up the drying time. It also works great as a temporary fix on drysuit seals.
Which Cotol version are you using? I find the plastic-filler-laden version (the one sold in the blister pack with a tube of AS) to be useless. The non-filled stuff works great but is very hard to find (usually have to buy 4 oz cans, though I prefer the 16 oz cans if I can find it.) Interestingly, McNett doesn't distinguish between the two on their website (or didn't when I was exploring the differences); had to call them to find the difference.
Drysuit seals: I usually keep a spare wrist seal and neck seal vacuum packed with a bit of sandpaper, some solvent as a degreaser (MEK, though acetone would do fine), and a tube of solvent-based contact cement. That takes care of a ripped seal (trim off old seal, glue to the remainder of the old seal.) It's a temporary fix, but a friend of mine is still diving his repair after 3 years (I can't get new seals to last that long - don't know hoe he does...)
For pinholes (or slightly larger), the pre-glued bicycle patches work well if you degrease or sand clean the area first. Tegaderm bandages work as well, but can be a b*tch to put on smoothly.
