I used Model Master flat white enamel to dull the car before applying Model Master rust enamel. I thought I mixed it at around 30% paint 70% thinner but this was just a guess for the test run. Now that I know more about what I'm doing I'll be more accurate with the mixes. I just bought 12 empty 4oz mixing bottles for future projects.What type and brand of paint are you using?
Several years ago one of our members said he practiced with his new air brush by using food coloring and spraying on cardboard and paper, just to get the feel of the device and procedures. I thought that was a good idea.
This is to emulate rust & road grim on a car Tom so a deluded mix of 70/30 is needed. This is only me first try at this so when I do accurate mixing in the future I'll let you know how it all works out.Well, 70% thinner sounds like it will be a bit thin. Experiment with what works well with each jar/can that you open. The thinner it is the easier it is for it to run. Do strain the paint, always. I use a 150 micron strainer bought from a place that specializes in paint for autos.
Though I can't really see the roof that good, I think it looks good.Your right great idea. I did not want that much rust on the roof but I guess it worked out. To heavy handed on the paint control valve. A little practice with some food coloring would of helped a lot.

Well, practice does improve any skill, but having your paint properly thinned for the job goes a long way towards getting it right as well.You pull back on the paint control valve to hard and you just aged the car 30 years. So I need more practice.
Due to the scale involved, a bristle brush is probably a better bet for that kind of graffiti than an air brush. At least, it would be for me.I want to draw the graffiti right on the car without any decals. We'll see how that works out. More practice.
