Ddl, I take it you are making muskie size lures ? The rattle cans are great if you don't intend making too many. If your making a fair few regularly then the spray gun is the way to go, you will need a different hose and fitting from your airbrush hose. I'm sure as big blue says, you'll get a suitable set up from harbour freight. We don't have harbour freight over here but I can have a look to find one similar to mine, this is basically a generic cheap gun, 1.4mm nozzle . Zinsser bin slightly thinned is still VERY thick compared with anything you could put through an airbrush. ..
