Actually....
Hairspray and petroleum jelly might actually work. For the hairspray you want Aqua Net aerosol can preferably the aqua or purple can. The stuff in a pump bottle doesn't work. The petroleum jelly would have to be put on very thinly and let dry. You can also use Chapstick or Burt's Bees applied very thinly. A glue stick applied thinly and let dry would work too. However, none of those are optimal. They are pretty much a back-up in case you have a show and forgot your deck and need to make one from stuff you can buy at Wal Mart or Target.
I'll send you a PM with what I use.
