Re: Upholstery maintenance
Armor All can cause some materials to lose elasticity or actually shrink, depending on what they are made of, and some of the vinyls and vinyl-type materials used on the exterior surfaces of cars/trucks/boats are harmed over the long haul. Instead of guessing whether or not your type of vinyl fills the bill, just skip ArmorAll and use something like 303.
Truck bed covers come to mind. The flexible ones that are hard to button are impossible to button when ArmorAll is used on them. If they are fastened and ArmorAll is used, the material is going to shrink/crack/split.
It makes sense that a steering- wheel wrap would suffer from ArmorAll, because that is the type of thing that is wrapped tight, and if it shrinks the only result will be cracks/splits.
