Can anyone tell me the difference between Frostin Pride & Pastry Pride? My local store carries both. I am primarily looking to use one as the base for a filling. Can either one be left unrefridgerated once the cake is filled and fondant covered for at least a day?

Many thanks for any info!

Ok, so in googling this info, I was led to several forum posts that I couldnt find when I used the search button (argh). This topic has been well covered.
