Really cheap airbrush setup question...REALLY CHEAP

[jo90]

OK, so I want to go airbrush route..however I want to see just how cheap I can do it.

I would want to source an Airbrush that is at least reasonable at controling a spray, but doesnt have to do pin lines etc...ideally just for light shadowing etc.

Airsource is going to be something like a Car Tyre...no compressors etc.

Anyone got any ideas on sourcing the airbrush, what other bits are needed (something I guess to connect the airline to a tyre's valve etc)

Really appreciate constructive replies loads

cheers
