I use luster dust all the time on fondant cakes and they all go in the fridge. I have never had any “sliminess” with my lustring (I love that word!). How do you apply your luster dust? I use PGA to apply mine – it’s 190 proof so it evaporates almost immediately after I paint with it. Also, have you ever tried bagging your cakes? When the cake is nice and dry, put a trash bag loosely over the top of the cake and tape it down in a few spots to the cake board. Remove the bag as soon as you take it from the fridge and it should really minimize the condensation greatly. I only do it on cakes that I’m afraid might run (hand painting, etc).
