The paint finishes applied today are much more durable than those available ten or fifteen years ago. As a result, even average care can yield great, long lasting results. Be aware, however, that the more you do to reserve the appearance and lifespan of your vehicles paint, the more sales and trade in value you will receive when it is time to purchase your next vehicle.
Washing
This is the single most important thing you can do to reserve the finish. Hand washing is by far the best, however, if you must use an automatic car wash, stick to those that do not have any brushes. Hand washing should always be done in a shady area and you will need a soft cotton cloth or chamois to dry the vehicle before water spotting occurs. (Note: If you have recently had a port or all of your vehicle painted, do not take through any automatic wash for 30 days.)
Products to Use
Stick with cleaning products that are designed and tested to be used on a cars finish. Most auto parts stores offer a good selection.
Avoid Parking Under Trees
Trees provide good shade but they are also the source of tree sap and bird droppings. Depending on what type of tree or what the bird ate that day, either can contain chemicals that will stain or even blister your cars finish if not removed promptly.
Keep Covered When Not in Use
The ultraviolet rays from the sun, over a long period of time, can cause cracking, blistering, and peeling. This is more true in the southwest than any other part of the country. Most of us do not want the hassle of using a car cover, however, parking your vehicle in a garage or carport can make a big difference in the life of your finish.
Wax
This will provide an extra layer of protection although it is questionable how long it will last in the hot Arizona climate. The added benefit is that when you are applying wax, you are doing a very thorough cleaning job at the same time. Always wash the vehicle immediately prior to applying the wax. (Note: Always wait at least 30 days before applying wax over a newly painted area.)
Paint Chips
Gravel roads can cause excessive chipping very quickly. Bug shields for your hood as well as mud flaps behind each of your wheels will help significantly. Parking lots will also cause you dings and paint chips apart you park far enough out that nobody is banging their door into the side of your car.
Professional Detailing
If you can afford it, have this done at least once per year. It will usually run between $ 100 and $ 250 for an inside / outside detail depending on condition, type of vehicle, and the level of quality you choose. A good detailer will take care of those hard to get at areas that are usually ignored.
