With Terry totally, I used them before I had the airbrush but you have no control of the spray pattern hence a lot of overspray and more paint is lost clearing the nozzle
But it is a SPRAY can. Decant? you would have to spray into another container with the accompanying blow back spray, i.e. paint lost then you would still have to spray the nozzle clear with more lost paint.
Would not a simple bottle of paint work much better?
