What is the best way to apply lots of luster dust. Thinking of covering pretty much the whole cake as a base on the fondant. Don't have an airbrush system yet. Will just using brushes work? Any suggestions on getting it to stick really well as I plan to pipe over it as well.

Thanks!

I haven't tried it yet (will be doing so this weekend), but I heard that if you mix some vodka with the luster dust in a fine mist spray bottle, you can lightly mist over the cake. I'm assuming you'd have to do it a few times (drying in between) to get an even coating.

Simply use a bigger brush If it does not need to have a high shine, dry brush it.
Otherwise you will have to mix small amounts at a time w/alcohol - vodka, extracts etc.
Have you ck'd out the spray cans - not Wilton's) that some places have? Can't remember any in particular right now......
