Wow, Matt, nice to see you!!
It's really personal preference whether you use a hair dryer or other method!
i don't dry mine with a hair dryer...I swear by the Sure Seals (www.alpglobal.com) for the wafer...they are waterproof and breathable so there shouldn't be any skin issues with that. As far as the pouch goes use a micro fiber type towel (like the small ones used for camping that dry really quick) and it should be dry in no time.
If you go online Sure Seal will send you a few samples to try...they take a little time to figure out but once you do, they're not hard at all.
Have FUN!!
