You are looking for the best in protection not just "shiney tires". With that in mind I fully agree with Aerospace 303, nothing else compares to it. It's uses are many including the dashboard and internal/external plastics & vinyl.
Here's a little blurb from them:
303 is THE LEADER in UV Screening Technology. 303 Aerospace Protectant really is like "SPF 40 Sunscreen ... For Your Stuff." Regular use gives 100% Prevention of UV caused slow-fade with regular use. No other "protectant" beautifies as intensely, protects as powerfully or lasts as long.
The World's Most Manufacturer-Recommended Product:
Because of its enduring cosmetic properties, the resistance of 303-treated surfaces to dust, soiling, and staining, its water repellency and unparalleled protective characteristics, manufacturers worldwide recommend 303 Aerospace Protectant.
303 Aerospace Protectant keeps UV-sensitive materials "like new" year after year.
I do not sell it nor am I affiliated with anyone that does. I do buy it though........ by the gallon.
