"orange peel finish"

Ron,

The pressure reading when pressing the airbrush trigger down doesn't matter as it's the setting when the airbush is at rest that people go by. At 44 lbs of pressure that paint is atomizing so well that it may be drying too much on the way to the surface of the train. Try spraying with the pressure set at around 15-20 psi and see what that does. I would think that the paint would be really thin at a 1:1 ratio and should spray easily without orange peel even at that pressure. Let us know what you find out.

Compressor starts off at 44pounds and when I press the air brush trigger it drops and stays at 16 pounds.Consistancy is more like milk . I mixed model master enamel 1:1 and sprayed at approximately 4in. distance. I have used both a med ium and heavy jet on the air brush. The heavy seems to work a little better. Thanks for the reply.

prime the bare metal first so the paint will have something to stick to and not "peel" off

Ron,

It could be a number of things: paint too thick, pressure too low, airbrush too far away, etc.

Give us the details and maybe we can help.

What pressure are you spraying at?

What consistancy is the paint? Like milk? Thicker?

I have had good luck spraying the Model Master paints in a 2:1 ratio of paint to Model Master thinner at about 20 psi.
