One of the most important things that you can do for your car is washing it. If you don't wash you car very often, dirt can build up on your paint and that can be really, really bad. Dirt buildup can actually damage your paint job and that can be a big headache to fix. Not to mention expensive. So if you don't want to have to shell out for an unnecessary paint job, then keep your car clean. You want your paint job to look good for many years to come. Paint also helps to protect against rust. Once you get rust, it will begin to eat away at the body of your vehicle and then you're looking at major body work and repairs. (Not cheap!) So get it washed every so often. Your wallet and your car will thank you. Plus, who doesn't love a nice, shiny car?
