I, too, have many colors of fingernail polish that I wish to use on cars. My question is how do you get the paint out of the bottle for airbrushing. All of the ones I have seem to have that sleeve inside the neck of the bottle that wipes the brush down to just having enough to paint a nail with. Of course, with that sleeve in there there's no way to pour the paint out so how do you guys get it out of the bottle??
