I did an aerialbot Slingshot nosecone and two of my three original Transformers toys - Fireflight and Blades - today and they came up great with no problems.
I was careful around the stickers but noticed when I was wiping the creme off the red came off the Autobot symbols on Fireflight's wings. These are the original stickers so it may well just have been age. I didn't notice any appreciable change to the other stickers (altho they are 20+ years old and a bit tatty to begin with).
