I'm thinking of airbrushing on some ganache but have a few questions..
Will using a compressor without a changeable psi be a problem or does it need a certain psi for ganache?
Do you do anything differently when airbrushing with ganache than what you would do with buttercream?.
Has anyone diluted gel colouring + Flo-Coat for airbrushing on chocolate? If so how has the colour come out on the white chocolate ganache?
I think I have already answered this question as best as I can. No airbrush of mine would ever have cocoa butter put into it.
Anna, here is the piece to which I was referring, made of modeling chocolate, which started out as a medium gray, painted with an airbrush with regular airbrush colors.

Water, that is why it was a little splotchy instead of perfect smooth. It wanted to bead up slightly on the chocolate. In the end, it did work well for this application.
I used black and a redish brown airbrush colors on the horse.
