Sealing & Sealant

What is automotive body filler for car repair professionals?

Body filler is a paste made from synthetic or natural substances that give the product both mechanical and aesthetic qualities for various finishing tasks. Automotive body filler is used in several industrial applications, particularly in the automotive sector, for:

• masking imperfections on body panels;

• providing anti-gravel protection;

• sealing joints between parts.

Formats of automotive body filler

Car body filler is available in several formats:

• In a can;

• Sprayable version (more fluid, applied with a spray gun) for hard-to-reach areas where a spatula can’t be used;

• Spray-on version for uniform application on large surfaces.

Hardener and catalyst

A hardener always comes with the filler. Acting as a catalyst, it triggers the filler’s reaction, speeds up drying time, and optimizes workshop productivity. Hardeners are sold in tubes and are formulated for each filler type.

Is applying body filler mandatory?

Yes, applying body filler is essential to:

• cover holes, scratches, cracks, and dents after repairs;

• shape and reinforce the treated surface;

• improve sealing and strengthen weakened areas;

• ensure a smooth, uniform, and clean finish.

The different types of automotive body filler

• Universal filler: suitable for all metal substrates, enhances weather resistance.

• Plastic filler: for trims, mirrors, covers, and bumpers; improves adhesion to plastic.

• Aluminum filler: made with aluminum powder, provides anti-corrosion protection; ideal for metal, aluminum, and polyester surfaces.
