I have 2 questions. I have to do a wedding cake for this weekend and I will be using pear luster on fondant accents. Have any of you ever just painted on the luster dust straight without using liquid? Mine always seems so blotchy when I mix it with a liquid. I was also wondering have any of you put luster dust in with your buttercream to make the borders appear pearl-like? I would appreciate any help anyone could give me.
Thanks!!!

you can buy a spray from either pme or wilton - in the uk it's £5.99 a can - it's invaluable - you just spray it where it's needed

Yes, I usually brush it on dry with a paintbrush since I have had the same problems mixing it with liquid! Brushing it on dry gives it a nice even layer of sheen. Here's an example.

Luster dust is light reflective so it must sit on top of the icing, it can't be mixed into the icing.

(Edited to add that the luster it gives is more noticeable than my photo shows)

I usually paint it dry. I usually tap the excess on the plate and then dust the accents.

I have done more dry than wet. Dry works fine.

I have seen the luster sprays as well, never used them.
