Many professionals use a clay bar when they are detailing a car. It provides a smooth finish. The surface of your car is constantly exposed to bug residue, tar and brake dust. If those things are not removed, then they can cause your car to rust. You may not be able to remove those things with regular washing.
If you use a clay bar, then you will remove contaminants and particles from the car. There are a number of factors that will determine how often you will need to use a clay bar. However, most people will need to clay their car at least twice a year.
You can tell whether your car needs to be clayed by running your fingers on the car. If it feels rough, then it is time for you to get the clay bar. Make sure that you take a look at our inventory here at Lewis Motors Sales.
