Plastic exposed to the sun turns dull and ugly after prolonged use. When this happens to the accessories of your car -- in particular -- the plastic has a worn-out look. Some examples of plastic car parts that get oxidised (and ugly) over time are the car's plastic bumpers, the side mirrors, and the dashboard. One solution would be to change the accessories, which could be costly. The same applies to fibreglass boats that after a while lose their shine and look old and neglected because of plastic oxidation. You can, however, regain the original shine and bring look of the plastic at a fraction of the cost of replacement.
The Miracle Coat is a solution that instantly restores plastic of fibreglass products to their original sheen and lustre. The product costs about £14 for a 59.1ml (2 fl oz) bottle, at the time of publication. It can be used to remove oxidation as well as buffable scratches. You need a microfibre cloth applicator (included with the product) with which you will apply the product and buff it just like you would with wax. You will need to reapply the product every six months to restore the shine.

A tried and tested home remedy is peanut butter. Wash the plastic with soap and water to remove all dirt and grime from its surface. Let it dry naturally. Take the peanut butter and spread generously on the surface. Let it rest for about 15 to 20 minutes. Wipe with soft towel thoroughly. It restores the shine and colour to any type of plastic.
