Okay, so tried something new. Wanted to get a gold luster coating on BC - so I let my BC crust and used a large, very soft (new) blush brush to lightly brush on...didn't like it at all....as you can see from the picture below it got "clumpy" and wouldn't "dust" on...
I've done this with super pearl before and liked it - any ideas....

bumping myself - need to do this tonight if possible....
I have painted with real gold dust and lemon extract on crusted buttercream, but only on accent piping. No photos of it, but I was very happy with those results.
As to covering the entire surface evenly, I have heard that luster dust can be mixed with alcohol and put through an airbrush. It's imperative that the airbrush is cleaned immediately and very well.
I have another thought that I haven't tried--what about putting some luster dust and alcohol in a small misting bottle and spraying it on? I have some bottles that allow you to control the size of the opening, so I'd think that the particle size could be accounted for and make it through the hole?
Needless to say, if you find a solution that you're happy with, please let us know!

What kind of alcohol based product would you mix luster dust with? I am using it for a child's cake.
When I "paint" with luster - I mix with vodka - even if for a child's cake - the vodka evaporates and leaves the gold dust behind...see my avatar cake for pictures of painting with gold dust...
I've never had a trace of vodka after the fact...

To paint, I mix with lemon extract--a little oil and an 86% alcohol content allows for good flow and quick drying.
If I were to spray, I'd be afraid the oil would clog the nozzle/needle, so I'd use vodka, gin, or Everclear. Virtually all of the alcohol will evaporate in the air and just the dust will be left behind--I wouldn't worry about it myself.

can you use vanilla to paint with luster dust?
I'd be careful about using extracts to paint large areas with, otherwise you will change the flavor of the product. Use alcohol and if there are personal reasons to not use it just paint accent areas with the extract. Remember that extract contains alcohol, in fact the % is pretty high, maybe as high as vodka.

WOW! I can't believe y'all are talking about this today! I've got a buttercream wedding cake to do for the 16th, and the bride wants it to be a champagne color. (I still haven't gotten to experiment with the icing color yet--so I have no idea HOW to get to this color--or where to start!)
But, I want to do the luster dust on the whole cake. I was thinking of a misting bottle, too. That's something I might actually try!
Here's the link to the wedding dress, if anyone has any tips on how to get to that color, I'd love to have the HELP!

I'll let y'all know how the spray bottle thing works!
