I used this for years on my car dash and other vinyl areas of the interior. I always thought it worked and protected pretty well although it does evaporate on to the inside of the windshield, which is annoying. It also doesn't seem to last very long and as it starts wearing off, the dash looks very dry.

I've since found&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/303-Aerospace-Protectant-32oz/dp/B004YJQE0S/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">303 Aerospace Protectant 32oz</a>, and that works much better. It doesn't seem to exhibit any of the aforementioned issues, ie., it doesn't seem to go on to the inside of the windshield, and the shine lasts longer.  It also protects from UV just as well, if not better.  Note that Vinylex contains silicone, which actually damages the vinyl/plastic over time.

 I'm definitely sold on 303 Protectant over Vinylex now although I really like the Lexol pH leather cleaner and Lexol leather conditioner for my leather.
