t least for a while. I bought a bunch of paint mix bottles with lids having a fitting to connect with the airbrush. Along with the bottles I bought rubber caps to go over the air brush attachment fitting. It occurs to me that now I can save my paint mix for touchup or painting a similar object at a later date without a messy transfer to another bottle. Or without the risk of a remix. I can cap the airbrush connection and plug the air hole in the bottle lid (probably tape it over) and the paint mix should last as long as it would had I poured it into another bottle with a traditional lid. I have not tried this yet, but see no reason why it will not work.
