I'm planning to do a lot of airbrush work on a large 3-tier cake. I've tried it in fondant before & it worked great, however I've only airbrushed buttercream cakes just on tiny spots here & there. I'm worried that if I do a lot of it on the buttercream (basically paint the whole cake) that colors might bleed or things will turn out differently. It's just going to be a demo (not for a client) but figured I would ask before I get started just in case (would hate to waste all that time!). So has anybody noticed any difference with the results between the two types of frosting???

I jsut did a Nemo cake. I did the different colors and it did not bleed. I first did my orange. I probably waited maybe 10 minutes between colors.
(The amount it took for me to clean the brush and then get ready for my next color.) It didn't bleed.
But be sure to use something to put over the other spaces so that you don't get color where you don't want it.

Actually fondant is alot nicer to airbrush on because it holds it's color deeper.I do find it you cross colors too much with both icings the colors come out like a yucky brown.Puddling will happen with both icings if you get too close also.You will be just fine!!

I've had problems with the color beading up on bc....so I guess maybe just be careful....give it a good bit to try before ya spray over what you've already sprayed.

The 4 tier orange cake in my pictures is all airbushed on buttercream.

If you look at my UT Football Stadium cake the football field itself is air-brushed all green and it is iced in butter cream it turned out great no bleeding

The last few cakes I airbrushed were buttercream....Heck--all of them were buttercream. 3D Spiderman bust was totally airbrused red. Just started and applied colors in layers. The "Sweet Sixteen" cake was lightly airbrused with black--didn't want a solid color--and then muted white rings were added in white.

I Air brushed Spiderman also with no problem and the sene on the side of the western cake with no problem

it will spray well on both icings, just dont touch it once sprayed and try to avoid putting it in the fridge as the colour will bead up when the cake sweats.
