I learned (and saw) something pretty amazing at the cake show this past weekend in Winnie, TX (and could have used the tip just one day before when I made an electric guitar cake that really needed some shine on it!)...you can spray Pam cooking spray on your fondant-covered cake to make it satiny looking.
Seriously, I never would have thought of spraying a finished cake with Pam, but it made the demonstrator's electric guitar cake look shiny and beautiful! After a couple of hours, the intense wet/shiny look dulls down just a bit to make it look satiny and lustrous. It was really pretty.
Can't wait to douse my next fondant cake in Pam. LOL!!
