I get that splatter effect by drilling out the nozzle to a spray paint can a little bigger. You'd have to cover the artwork. Practice on scrap wood first to get the distance. I spray it in short bursts. I did a shuffle alley like that and it looked great when it was finished.
That's an interesting idea !
I have a Pac project that I was trying to save the art on (sadly, the combination of multiple layers of gray and black, in both oil and latex, along with primer made it impossible) and have a set of vinyl sideart that I plan to use. Problem is that it's an 'oops' printing -- purple instead of blue for the ghost.
I decided I liked the purple (it's the uber-R@RE, Pr0ToType Purple Ghost version!) and was thinking about purple splatters.
Thanks.
