PBA Tip of the Day brought to you by Bill Slis with The Finished Look(623) 451-5052.When it comes to the question of how to keep your car shiny, overall weather conditions can play a huge part in the process. Arizona summers, which are often hot and dry, can wreak harm on your car’s finish. The UV radiation can oxidize the surface of your car, causing the paint to fade and lose its luster. Therefore, if you don’t have a garage or are away from one, keep your car parked in a shady and sheltered area. It also helps in preventing your car’s headlights from yellowing and rubber trim from turning brittle and crackly.
