You can paint it with gel color mixed with vodka and it will be shiny for a few days, or paint it with confectioner's glaze and it will be shiny forever.
You can paint it with a mixture of water and gum arabic.
When added to royal icing gum arabic strengthens it a lot.
Seems there are a lot of ways to achieve this. I'll try the steaming first, since I won't have to purchase anything. If that doesn't work, I'll move on to one of the other methods.
I'll have to look into gum arabic, too. I haven't used that either.
Thank you everyone!!
I've been experimenting with this too and I can tell you what did NOT work...painting it with glycerin. It stayed sticky for weeks...by the time it dryed it wasn't shiny any more! and Crisco didn't work very well either...hard to get it into the crevices. HTH!
Gum arabic is cheap. When you might be ordering something from Global Sugar tack on a bottle--it's worth having on hand. Or it might be a good excuse to work up a juicy order! 
Gum arabic is easier to clean up than confectioner's glaze too. Not as shiny, but less mess and less smell for sure.
You can make cake glitter with gum arabic too...mix it with a bit of water and food color, add a pinch of luster dust if you want, spread it very thin on a silicone baking mat and bake at a low temp until it's dry. Let it cool and then break it into flakes. It looks just like the large, clear flakes that Wilton sells
Shiny fondant question!
How would I steam my fondant bow topper? I guess I need a steamer?
I've already made the bow.. half gumpaste/half fondant... Any ideas?
