i use either the got 2 be glued freeze spray, or rave x4 spray...and i can fold it up to lean back in a chair and it will spring back (up to resting on it like that for 15-20 minutes) if it's longer than 30 minutes max, well..not much you can do but to carry hairspray/blowdryer with you lol.
I've found that water helps at least a little for some touch ups...damp your hands and use them in a clamping, straightening motion up your hawks' length.
