For vinyl and plastic interior surfaces, I prefer Vinylex from the makers of Lexol leather treatment. http://www.lexol.com/vinindex.html It has a UV inhibitor in it and seems to do a good job of protecting the surfaces I've used it on. I've seen it for sale at various auto supply and hardware stores. 303 protectant (available at boat and pool supply stores) is another one that is very good. Also has a UV inhibitor and is better for outdoor use than Vinylex. A lot of the convertable drivers love it. http://www.teammiata.com/303products/vinyl.htm has more info.
