Maintaining your vehicle’s paintwork is very important to maintain its shine and appearance for a long time, but how often should a vehicle be polished?
The first thing you should know is that maintenance should be done depending on how damaged or neglected the paint, so if you have a relative periodicity in the waxing you will avoid resorting to a polishing process.
The polishing of automotive paint: Difference between waxing and polishing.
The difference between a waxing and polishing is significant for the paint film since a waxing creates a protective layer over the paint film and fills the micro scratches that can be found on the surface. A polish does not fill scratches, but rather generates them on the surface. Take into account that the polishing or rubbing is an abrasive product that was designed to make a wear of the surface, as does a very fine sandpaper, and that serves to remove the oxidation that eventually takes the film paints.
The polishing of the paint removes the oxidation, returning to the paint its appearance and color, but also removes part of the paint in good condition, making a wear of it. This wear cannot be seen in the transparent paint films of the bilayer paint systems that are present in the vast majority of vehicles.
If it is taken into account that the thickness of the varnish layer of the vehicles is approximately 2 mils thick, equivalent to one third of the thickness of an average human hair, then the microabrasion generated by the polishing means accelerated wear for the paint film, which cuts its duration over time, then it becomes important to polish the vehicle as little as possible.
The polishing of automotive paint: What should be the periodicity of vehicle maintenance?
Monthly waxing, which creates a very smooth layer in the paint film and which helps to keep the vehicle protected against the accumulation of dust, smoke, and oxygen in the environment, avoiding the oxidation of the film and the accumulation of polluting residues in the same.
Polished twice a year at the most, to eliminate oxidation and residues of dust and smoke that may have accumulated on the paint surface, preferably with a fine-cut polish so that the abrasive capacity is less and therefore less the wear generated in the paint.
With this maintenance routine, your vehicle will look bright and the paint will last for much longer.
