My Model Master RAF Sky Type S was dried up. Luckily, I had Mission Models Sky. At first, I tried spraying thru the airbrush and it wouldn't spray. I thinned it with Mission Models own thinner. Strange....
I emptied the cup and poured it in medicine cup. Huh.... I swirled as added more thinner. I see grainy bits on the bottom. Wow. Mission Model thinner musted have been so old it had a reaction to the paint.
Cleaned out the cup tried again and thinned with water and it worked fine. Went back again and put a second coat of Sky.
Propeller tips I used RAF Trainer Yellow.
