Pardon me for posting a bit of a dumb question, but I recently read an article about thinning paints and the author wrote that the best method is to thin paint in a mixing jar before transferring it to your airbrush of choice. Now I always used to mix my paint in the color cup of the airbrush and had satisfactory results but I am willing to try this "new" technique out.
However, I see this to have the potential to make more mess than its worth. Assuming I am using enamel paint, I could see me using more paper towels and lacquer thinner than I would if I just mixed it in the cup.
So I am putting it out there to see what you guys/gals do.
