You didn't mislead anyone Crewella.

I would have thought they were safe myself if I didn't know any better. (And I didn't know any better till today. Lol)
After all it does say rubber care.
Hell even ugobe and innvo labs unknowingly gave people faulty advice.
Now we know going forward what to use. Im still in contact with GLS as of this afternoon so I will be discussing ways to have new skins made with a homemade reverse vacuum mold if need be. I will post any updates in this thread.
NOTE:
I really think to cut down on any confusion in the future that this information about Gibbs and the other alternatives should be used in a sticky on the forum or perhaps an FAQ so that when this thread gets archived the info will not be lost.
Surprisingly even BMW Gummi Pflege is silicone-based. It's good in the short-term but destructive in the long term. Do not use on Pleo.
Because many treatments for rubber do include silicone, which is great at making rubber look good - for a while, but not so good when it comes to dust and dirt. Silicone acts like a magnet, attracting dust and drying out the rubber.
Im not sure about the new spray on Gummi Pflege since its made by another company now and not BMW but I wouldn't take any chances...
Update: After asking Einszett (the maker of GP) about this I got the following response:
"Thanks for your question about Gummi Pflege and sorry for the confusion. Gummi Pflege contains a water based silicone. What it doesn't contain is silicone oil. "
So Gummi Pflege, Vinylex or Autoglym are out.
Gibbs seems to be the go to choice.
