Do you all have any experience painting buttercream? My daughter wants a resplica of a bass fish for her boyfriends birthday this year. I want to cover it in fondant to make it easier to paint the coloring on it. She prefers buttercream because she doesnt like the taste of fondant. I dont have any experience using different colors on buttercream and I dont have an airbrush machine (yet!).

Thats replica, not resplica!
