How to Choose Auto Body Abrasives for Repairs

Accidents, improper parking, inclement weather, and poor driving can damage the body finish. Minor dents do not interfere with the use of the vehicle. But they spoil the car’s appearance, making it old and sloppy.

Choosing suitable auto body abrasives will help you get the perfect result and make your job much easier. There are a considerable number of tools and materials that are suitable for various positions.

Graininess: What is it

Grit is the primary indicator when choosing abrasives. It starts at 40 and ends at 600. The smaller the number, the rougher the material. The most effective body treatment is worth starting with the most significant indicator. Thus, you can adjust the intensity of the abrasive and avoid deep scratches on the body.

In the catalog, you will find three types of grit:

  • low;
  • average;

A score less than 40 is low grain. For example, it is suitable for leveling the car body if several coating layers have been applied. Abrasives with indicators of 60-80 are used to remove rust and minor scratches. Options with a hand of 300 are used to process sharp edges roughly.

Medium abrasives have a designation of 400 to 600. They are ideal for preparation before applying paint. This option aligns the base well, which allows you to get a perfectly even and smooth coating.

Abrasives with a high index can be used for the final sanding of the car body. Variants with a grain index of 1000-1200 are excellent for leveling the paint after drying. To avoid the appearance of micro-scratches, the wet method of applying the abrasive is best.

How to Choose the Suitable Abrasive

In the DealerShop catalog, you will find abrasives for car bodies with different grit levels. But do not buy the first available option. Otherwise, you risk ruining the coating. When choosing an abrasive, consider:

  • type of material to be processed;
  • desired processing result;
  • features of the use of abrasive;
  • price range.

Usually, the manufacturer uses a label that indicates what kind of work the sandpaper is intended for. It will significantly simplify the search for the desired material. It is essential to use a suitable abrasive so as not to damage the body and not provoke its further destruction.

Different materials are chosen depending on which part of the body needs to be processed. Accordingly, additional equipment may be needed. For example, a particular machine is required to work with disks, and grinding blocks are used manually.

The expiration date also plays a big role. Some options can quickly become clogged with particles of paint, metal, and other materials. Because of this, sandpaper will be less effective.

DealerShop consultants can help you choose abrasives ideal for your car body. It is the easiest option to select quality materials and not overpay simultaneously.
