I know this is an old thread but hopefully someone sees this! LOL. I have never airbrushed cookies before but really want to start learning. I see all these cookie/cake decorating airbrush kits with little tiny compressors but if I already have an air compressor (it's much larger at 6 gallons) can I just buy extensions to use in order to use it for airbrushing? I hope that makes sense. Sorry if it is a dumb question. TIA!
