i airbrush on buttercream crusted cakes a lot....and i use this sort of technique ....undercoating then blocking out spaces...look how fast it goes once you get the simple concept down...

this could be a cool background for a star wars type cake.

of course it's a somewhat different using an airbrush than a spraycan...but you get the idea.

Wow thats really cool! You could use the Wilton spray cans to do the exact same thing!
Hmm I'm thinking about my next cakey purchase now

I love these. They do them on the streets of NYC all the time. It amazes me how quickly they come together.

How funny! I have an awesome painting hanging in my living room that was created with the same method. I never thought of doing it on a cake.

wow!! that is really cool. I would never think it can be done in minutes...
thanks for sharing

Thats cool the Bob Ross of the spray can.
