This is how you can bring most faded plastics back to life on your car. Be sure to try this method on a tester patch that is hidden to make sure that it doesn't damage your plastic before starting on any visible areas.
This method can be used on most of the plastic trims on your car that aren't painted such as mirrors, bumpers, wheel arch covers and much more.
The car which I did this wing mirror on has been sat out in the elements for at least 15 years as you can see by the state of the it.
