Hey Bill,
I would go with Meguiars Quik Interior Detailer.
It leaves an original/matte/factory look.
All you have to do is mist and wipe it over the surface. It leaves a nice, fresh clean scent and can be used on leather, vinyl, clear plastic, etc.
It does leave behind some UV protection but not as much as a traditional dressing.
It really does not leave behind any sort of gloss or shine at all.
Do you have it already or have used it before?
