I'm looking for advice from people who have successfully repaired neoair mattresses, or at lease people who know more about materials science than I do. I have a pinhole in my mattress. I don't want to buy the "universal" patch kit from Cascade Designs: I have a half-used, pre-neoair patch kit already, so I don't want to buy a whole new kit with things I will never use just for the sticker that repairs the neoair.

This information is corroborated by (or taken from) this post at Mountain Equipment Coop: http://answers.mec.ca/answers/9421-en_ca/product/0899-120/questions.htm . That sounds good: what I'd like to do is use seamgrip and one of the nylon fabric patches from the old therm-a-rest repair kit to repair my pad. Can anybody confirm that this actually works? Or do I need a different fabric, maybe a film rather than a woven, such as one of the tapes named in the BPL post?
I've also been looking at alpacka repair, since my understanding is that both the neoair and alpacka rafts are urethane-coated nylon. I have an alpacka patch kit, so I could also use aqua-seal on the pinhole, or use aqua-seal + patch-n-go. See http://www.alpackaraft.com/index.cfm?section=repair-and-custom&page=Field-&-Home-Repairs&viewpost=2&ContentId=2622 . I'm worried, though, that treating the neoair and an alpacka as equivalent is a case of a little knowledge being a dangerous thing.
To summarize: should I repair my mattress with (a) seamgrip + nylon fabric from therm-a-rest, (b) patch-n-go + aqua-seal, (c) some other combination of the above, or (d) something else (that I'd have to buy).
Thanks, and sorry if there has been a more recent discussion of this that I somehow missed.
