Life of a clay bar

[Tireguy]

How long will a clay bar, Mothers little yellow one, last? Like how many times can you do a whole car with it?

It really all depends on how bad the car is, and how bad the clay bar gets dirty. I usually, when I first buy the clay bar, tear it in half. I usually use one half of the bar per car (2 cars per clay bar). I have heard, and believe you can do 3-4 Average sized cars with one clay bar, but again, it depends on what the shape of the clay bar is in after use.

I've used my claybar on probably 20 cars. It all depends on how you use it and take care of it.
Keep it dry when you're not using it.
Keep the surface of whatever lubed when you are and make sure to fold it often to keep a clean clay surface.
