What should i use (hairspray?) to fix oil pastels?

go to your local craft store: Joanns, Pat catans, michaels, etc and look for oil pastel fixitive, i have used this http://www.blick.com/zz217/13/ , along with many others before... just make sure that it is NOT workable fixtive, that will still allow smearing but reduce it while you are not working on it/to get too muddy of colors.
