I have made a few display cakes for Bridal Fairs and ect... There is too much humidity in my tasting room for some of the more delicate Gum paste work to survive for long and I don't want to quickly loose all that work. Can I spray something on them to lock moisture in with out effecting the look of the cake?

Thats a great question!! I await the answer!

i know some people spray their with varnish, but i cant say if that would help against the humidity, seeing as britain does really have any!

Sorry, I can't answer your question but it reminded of this. There is a small candy and cake supply shop near me that has display cakes in the window. I stopped in once to check it out and to pick up some dragees and those cakes were so dusty and faded! Just nasty! I would love to know how long it's been since she's had a cake order and if it ever crosses her mind why!

I was watching Amazing Cakes (is that the name? on the WE channel?) yesterday and the baker in Orange County (Garret?) was doing a consult and most of his dummies are in glass fronted cabinets.
Don't know if that is to protect from the elements (beach community) or curious fingers. Probably a bit of both.
MS had this as a "Good Thing" a while back...spray with some of the old school hairspray. Sounds iffy, may just be a dust magnet.

Why not make displays with clay or playdoh? That way it is permanent. No one will eat it, and any "sneaky fingers" will get quite a surprise....

After all, gumpaste work is sculpting- just with sugar instead of clay....
