    If you mean something like this
    https://mangoinc.com/spray.jpg
    It was done with device under $5 from an art store called
    an atomizer. It looks like 2 metal straws at a 90 degree angle. Dip
    one straw in India ink and blow from the other. It’s healthier
    than a spray can and not as messy.

    Boris has a good noise filter for animating the effect. In fact,
    the Boris package is gigantic now. One of the greats along with
    Tinderbox and Trapcode – and of course, Digital Anarchy.

    [jean hauptman] “Boris has a good noise filter for animating the effect.”

    I looked at BCC’s noise filter and would appreciate a word or two from you about how you’d use it to animate the effect. The atomizer tip is good.

    Bob-

    This is a quick hack using BCC Spray Paint Noise
    https://mangoinc.com/bcc_spraypaint.mov

    The noise layer was matted to an animating feathered solid.
    There was a second layer over that later for more density.

    Noise seed was animated a little. Perterbation and percentage
    were also animated.

    This isn’t beautiful – you could do better with a little more time,
    and get more elaborate with spray strokes.

    this morning, I was doodling around with bcc spraypaint and updated the original
    mov posted above.
    This just has added strokes from vector paint.
    below the stroke layer, the bcc spray was matted to a heavily blurred version of the stroke
    layer to add spray to the edges.

    Very cool movie. I’ve been sitting here trying to duplicate your it — unsuccessfully.

    As with a lot of BCC, I feel as if I can’t do more than scratch the surface. The relationship of Perturbation and Noise Seed eludes me; why does increasing Perturbation erase the impact of changing Noise Seed? Changing the paint color, for example, doesn’t seem to matter.

    Would you mind sharing your .aep, or recommending a tutorial source, so I can see where I’m going wrong?

    Bob-
    I have a project for you. Let me know your email address, and I’ll send it.
    I eliminated the splatters and background which are copyrighted.
