Is the paint on your car chipped up? I live on a long dirt road that damages the paint on my car every time I have to drive on it. I have gone through several cars over the last twenty years because they would all rust out long before the motors went bad. What I found out was that my cars were rusting because the paint was chipped and it left the metal exposed. Once exposed, the metal quickly corroded. I have learned a lot from my auto body mechanic to help me protect the paint on my car after he did a complete paint job on my current car.
