I have a 50th anniversary cake coming up in December and the client wants a buttercream iced cake painted gold. I've seen cans of gold luster spray but I have never tried it. Before I order some to try out I thought I would ask others if it worked well or at all.
I've used it and well...didn't work for me! Plus to do a whole cake would be EXPENSIVE! If you have an airbrush system I'd use that. I HAVE however, painted a cake gold (buttercream) using a mini foam
roller! Worked well for me!
