It was no big deal Mike, I get strange looks in public anyway!!! :-)
Another trick that I've had backfire (literally) on me is one I learned from the old days of spraying automotive paint...
If the airbrush clogs up, you close off the end of the brush and hit the air...since the tip is closed off (usually with a paper towel), the air is forced back into the brushmoving whatever is clogging the brush back into the paint cup. This is handy if you're almost done or doing a small part, since you can generally spray for a few more minutes before it inevitably clogs again. Kinda like trying to drink a strawberry milkshake through a straw.
Anyway, I hit the air a bit too much, and got the same effect as blowing the paint into the bottle. Nice splatter effects can be achieved on yourself, the model, or anyone standing within a 5 foot radius. :-)
