AA has been water based for year now. I don't know of any common protectants that are silicone based (probably are some). Most are water based these days. Personally I'd stay far away from AA as well.Btw, I would recommend against using Armorall of any sort. Anything that's oil based will repel water and dry out plastics so once you apply it, you're forced to use it to keep the plastic moisturized. You're better off using something that's silicone based.
