Some people may see a wax job as an extra for their car, something you do on special occasions to provide a little extra shine. But waxing your car is actually something that should be done on a regular basis. Too often car owners provide regular maintenance on the engine of their vehicle and ignore the exterior altogether, save for a few trips through the gas station car wash. The exterior of your car needs regular care as well. While neglecting the paint job may not lead to mechanical performance issues, it will result in a lower resale value, just like if you never changed your oil or got a tune up. Regular exterior maintenance will keep your car looking new for years after purchase.
