Which Abrasive discs should I choose?

In this guide you'll find everything you need to know about Abrasive discs for bodywork. This tutorial is divided into several parts. For beginners, you'll find a detailed explanation of Abrasive discs, followed by the types of discs available on the bodywork market.

What are Abrasive discs?

First of all, we need to define exactly what an Abrasive disc is. Circular in shape, Abrasive discs are solid and can cut. The basic function of an Abrasive disc is to sand, in other words to smooth out or correct an irregular or flawed surface on the bodywork. This can be done on both metal and plastic. More experienced bodybuilders will also tell you that an Abrasive disc can be used on Clearcoat (if you want to remove it from the bodywork) or on primer if you want to even out the surface you are about to paint. All the possibilities mentioned above are just an introduction, and you'll discover a much wider range of possibilities later in this article! Abrasive discs can be fitted to an electric or pneumatic sander.
As you will have realised, choosing the right equipment and practising the right technique are essential if you are to achieve the best possible end result. Your polishing discs will come in handy on many occasions during your bodywork touch-up!

Below are the different Abrasive discs available on the market, classified according to their role in bodywork refinishing.
