I am making a buttercream cake. On the top I am placing a blue & gray badminton racket made of fondant. I hardened it by adding Wilton's Gum-Tex. My customer is picking up the cake tomorrow (Weds night) and serving it on Thursday morning. I normally place object on the cake as close to serving as possible but since it's going to be all put together for more than 12 hours. My question is will the blue & gray fondant colors leach out onto the cake? If so is there any thing I can do to prevent this?

Thanks much for your help!

there should be NO problem

No worry. The fondant will hold the color in and stabilize it.

Thanks. A relief. I have peace of mind.
