I was having problems Wojtek with some AlClad "Dull Aluminum" when spraying larger areas going splotchy/pasty I was about to ditch the bottle as old.I like to paint the blades and spinner silver first for when I like to chip.I said well let me thin it with MrHobby leveling thinner and it fix it laid just as smooth.I put two drops in the Dark Aluminum for the exhaust panels sprayed smooth as silk.I am using a New Airbrush for smaller areas a Badger Velocity gravity fed can spray a 1/32" for me thus far they say thinner.
