can I use wilton airbrush in a can on MMF?

I used it on my baby shower cake this past weekend and it worked fine. I covered my cake board in fondant and used the spray cans to give the fondant a plaid look. It worked fine. Just be sure to put paper down under your cake because you will get some overspray. Good luck.

Just start slow and build on the color gradually so it doesn't run. It should work just fine!
