Common Defects


Your car will collect some sort of contamination on the surface of the paint work from just about anything, it would be impossible to avoid it. It is down to particles in the air sticking to your paintwork causing a rough or gritty texture. All paint finishes are affected by contamination and over time could oxidise and therefore cause rust. Washing or waxing alone will not remove them. Your two main options are to machine polish or a clay bar, both will exfoliate contaminates from the surface of your paintwork.


Where does contamination come from:

  • Water spots
  • Brake dust
  • Paint overspray
  • Tree sap
  • Bug residue
  • Industrial fallout

Swirl Marks

Swirl marks are the main defect in any paintwork and are caused by incorrect washing methods. Washing with a sponge traps grit between the surface of the sponge and your paintwork therefore dragging sharp particle across the surface, also can be caused by automatic car washes. Swirl marks detract from your vehicles paint finish causing dull and lifeless paintwork, these can be completely removed by using different grades of compound and machine polish.


These are caused by many different situations, these can usually be removed in the same way as swirl marks. Using the different grades of compound/machine polish the scratch will be removed (depending on how deep the scratch is), if the scratch is still visible after being machine polished the next stage is to wet sand the area then repeat the machine polishing process. If the scratch is too deep and can be felt with a fingernail the area will need to be re-painted.

Stone Chips

These generally cannot be removed by paint correction, the best way to remove a stone chip is with a high quality touch in pen. The stone chip can be filled, then wet sanded and blended to match the original paintwork.


This is most common with red paint, it is caused by the sun oxidising the paintwork. In some cases the paint on a car will fade, become very dull and even lose it’s colour. These paints are often single stage paints and do not have a clear coat lacquer to protect them from the harsh elements. Paint correction is required to remove the oxidisation and restore the paintwork back to it’s original condition., this can also be prolonged by using a good quality polish and wax/sealant.

Buffer Marks

These are caused by poor machine polishing, they are usually seen in a specific pattern in the paintwork (either an up and down or backward and forward motion). Buffer marks are generally found on vehicles which have just had paint/repair work done on them, easily removed with the care of compound and machine polishing.

Bird Droppings

Bird droppings can quickly cause damage to your paintwork, bird droppings are very acidic and will burn and etch the paint’s surface. The longer it is left on your vehicle, the more damage it will cause.

Always remember

Healthy paint is the foundation of a good-looking, well-detailed car.
