■Clay composition and purpose of use
There are various clay bars which remove iron dust and paint overspray from a vehicle’s body. These colorful clay bars have distinct physical properties which are well suited to different jobs, allowing for a higher level of detailing. However, there are some products sold on the market which simply have different colors but purport to have different uses, even though their physical properties are exactly the same. Furthermore, some products have a range of particles in the clay bar and claim that their advantage is in being able to handle all kinds of jobs. However, due to the properties of clay bars, it would be difficult to give them such characteristics.
