I have patched a number of rips in both neoprene and breathables. i have always used aquaseal and I have NEVER had to sew the rip, that seems pointless to me. The only time I have had to use a patch was puncture of a breathable set that went straight thru.
I would not recommend putting duck tape inside, your feet often get hot and sweat, I think duct tape would eventually come off leaving a big sticky mess behind.
Are you patching neoprene, and if so is the hole all the way thru? if it is I would do it in 2 steps - first use glue to join both sides of the hole back together, let it set 24 hours, then masking tape off an nice square patch, apply aquaseal over the repaired area, let it sit for and hour or two and remove tape, let second application set 24 hrs too.
Aquaseal goes on thick and then runs/flattens out after application. masking it will help create a nice clean looking patch instead of some "globby" looking hunk of glue.
Simms has a repair kit that includes one small tube of aquaseal and a 2 inch over patch, if you think a patch inside in neccesary, use that kit. from the inside put glue over the hole then center and apply patch, let it sit 24 hrs, flip right side out, mask off rip and repeat steps above.
BTW I have bought aquaseal tubes that essentially dried up after the first use so the larger $8 dollar tubes may not provide and more repairs than a smaller tube in the simms kit that contains the neprene patch...they are both roughly $8 at Pacific Angler.
