303 Aerospace Protectant is a great choice for a factory look on most vinyl and plastic interior surfaces. Another good option is Werkstat Satin Prot; in our experience, this truly is a factory finish product, and works great even on fussy soft touch materials (think Audis). Three different sizes of 303 can be slected in our store, including a sample size if you want to try it out before you commit to a big bottle...
