On a bit of a side note, washing your car regularly is also very important. It is probably more important than waxing it, especially if you live in an area where the roads are treated with salt in the winter. I have added car washing to my weekly routine. I use quarters that I get back from going through drive up windows to wash the car each week. It only costs me about two dollars and five minutes of my time, but will add a lot of life to my car
