Yes , ive got a single action external mix airbrush , you know the cheap suction type with the conical brass nozzle that just pokes up into the airstream . Ive been experimenting with this and it seems to work fine, the advantage of this type is that there are no seals to be affected by the cellulose , and no moving parts that are in contact with the paint so its easy to clean and less prone to blockages/ drying .ive even had a go spraying some with quite large flakes of glitter in them with reasonable results.Interesting, so what will you use for thinners ? cellulose ?
