I'm using my air brush for the first time in years to paint a tender gunmetal gray for this engine. My question is after the first coat, can I leave the paint in the air brush bottle and just seal the opening that goes into the air brush? I want to do a second coat tomorrow using the same paint and don't want to throw it out unnecessarily. I did clean the air brush by running some naphtha through it after painting.
The paint is Henning's gunmetal metallic. It is not an exact match to the engine so far, maybe the second coat will darken it a bit. It will still be nice to have a tender. I managed to get a spare, that is why there are 2 tenders in the picture. Only one has the proper drawbar though.
Appreciate any tips on mixing, using and storing paints for an air brush. Thanks!
