Preparation, preparation, preparation... is the key to achieving amazing car care results. No matter how good your fancy wax is, or how many coats of it you apply, you will not achieve a perfect finish unless you spend time preparing your paint properly. Proper preparation involves two key steps. In the first, firmly bonded surface contaminants are removed using tar removers and detailing clay, to leave painted surfaces feeling perfectly smooth. In the second, sub-surface defects sitting below the paint surface are removed by polishing, which is a broad term for a range of processes that remove or mask paint defects and enhance surface gloss in preparation for the addition of protection.
The polishing step is often skipped or misquoted by many car care enthusiasts (in the latter case we mean that many people often say they have polished their car as a catch all term for whatever they have done to it). This may be because they do not fully understand what polishing does, or because they are not confident enough to try it, or because they believe it requires equipment that they do not have. As a result, many enthusiasts are left dissatisfied with the appearance of their paint. In this guide, we will attempt to shed some light on the subject of polishing by (i) illustrating common sub-surface paint defects, (ii) describing the different types of polish currently available on the market, (iii) demonstrating how to polish paint by hand and (iv) demonstrating how to polish paint by machine.
What do we mean by sub-surface defects? Sub-surface paint defects are any forms of damage that are cut into the uppermost layer of paint on your car, and include marring, swirl marks, scratches, stone chips, water spots and acid etching caused by bird droppings and bug remains. By far the most common form of sub-surface defect is stone chips, particularly on the front ends of cars. However, many paint finishes also suffer from swirl marks and etching, and scratches are almost guaranteed if you park in supermarket car parks on a regular basis. Another less common form of defect is buffer trails or holograms, which are lines of swirl marks inflicted by poor machine polishing attempts.
