The 8 most common mistakes when selling your car privately in Australia — from overpricing to the Notice of Disposal most sellers forget to lodge.


Ever washed your car, dried it off, and ran your hand over the paint only to find it still feels slightly gritty? That’s where clay barring comes in.
At Carma, we know that great car paint protection is about more than just a quick soap and rinse. To get that "glass-like" finish, you need to remove the microscopic surface contamination that a standard wash leaves behind. If you’ve never used a clay bar before, don’t worry, it’s a simple DIY car detailing task that makes a massive difference to your car’s shine.
Before we get started on how to use one, it’s a good idea to understand what it is. It is a putty-like tool made of synthetic resin. It is specifically engineered to pull out contaminants that are bonded to your paintwork, things like tree sap, stuck dirt and stubborn bug residue.
There are generally two types of clay bars to choose from:
You don’t only need just a clay bar to clean your car. These other things will help achieve the best result:
1. The prep wash
Before you start clay barring, you’ll need to wash your car thoroughly to remove loose dirt and grime. Dry the car completely and park it in a cool, shaded area.
Working in a small section, spray your clay lubricant onto the paint and the clay bar itself. Never use a clay bar on a dry surface, this is the quickest way to damage your car paint.
3. The claying process
Gently glide the bar back and forth over the lubricated area. You will likely feel (and sometimes hear) the clay "grabbing" the surface contamination. Keep moving until it glides perfectly smooth.
4. Re-mold and refresh
As the clay picks up dirt, fold it in half and knead it to reveal a fresh, clean surface.
5. Check and repeat
Run your fingers over the section to feel the difference. Once satisfied, wipe the area with a microfibre towel or chamois and move on to the next panel until the whole car is done!
