IF you don't have an airbrush to work with this paints, you can buy the "Testors" set that includes the aerosol can, a plastic airbrush (really easy to use), two empty glass bottles, adapters and other stuff and of course the air hose.
Total cost for it...around $10-$12 available at both Walmarts or Hobby shops, and you don't need a compressor cause it comes with an aerosol can, that you could just detach the hose from the can when not in use and you're good to go. My 2 cents.
