Spray Paint / Spray Can Effect

I want to create a spray paint brush that has the same effect that you get from a spray can within Photoshop. I messed around with various brush effects with the airbrush option enabled, but I can’t seem to get a real spray can effect. Another problem that I see is that I don't get enough dispersion, what mean by that is if I have a 50px brush, the maximum dispersion I get is 50px, so I never get a true spray paint effect.

Does anyone have any suggestions?

Do a search on this forum for "airbrush". May not directly answer your question, but several posts have good insight into how airbrush works.

Here is one link. <http://www.adobeforums.com/webx/.3c063589/6>

you need a pressure sensitive tablet.

I own a Wacom and I also have tried the stock "Transparent Red Spray Paint" brush from the tool preset. It just don't have that real spray paint effect.

Anyone else got any suggestions?

Yeah, get Corel Painter.
