some surface scratches without visiting a specialist workshop.
Why do scratches appear and how to identify them?
Before working on the car’s paint, it is important to understand what type of scratch you are dealing with. The bodywork is made up of several layers: sheet metal, an anti-corrosive primer, the color layer and, above all, a transparent varnish that protects the color and provides gloss.
Scratches are mainly classified into three types:
Surface scratches: These affect only the varnish layer. They are among the most common and may
suitablefor
careful home polishing.
Medium scratches: These pass through the varnish and reach the colored layer. They require more work, although their appearance may sometimes be reduced.
Deep scratches: These reach the primer or even the metal. In these cases, professional repair is generally advisable.
To get a basic indication of whether a scratch is superficial, gently run your fingernail over it. If your nail does not catch on the mark, it may be a shallow scratch that could potentially be improved using a polishing foam method.
