i share the exact same problem. and right now i also only have a
bottle of gatsby wax. 
according to my hairdresser, you put a little bit of whatever you
are using in your palm and spread it around both palms. then you
run it through your hair so its even and after that just use your
fingers to style. how you style and spike depends on you and your
hair le.
i hope some hairstyling pro puts a guide here of something
LOL.
