U-POL EXTRA is a versatile, high-performance 2K multifunctional polyester filler engineered for a wide range of automotive repairs. Known as a "hybrid" filler, it combines the high-build filling capabilities of a heavy body filler with the smooth spreading and easy-sanding characteristics of a finishing glaze. Its light grey color provides a neutral base that is easily covered by primers.
Key Performance Features:
- Multifunctional Application: Specifically designed to handle everything from medium-depth dent filling (up to 4–7mm) to fine surface finishing in a single product.
- Smooth Spreading: Features a creamy, "Extra" smooth texture that glides onto the panel, significantly reducing the effort required to level large areas.
- Pinhole-Free Technology: Formulated to minimize air entrapment during mixing and application, resulting in a dense, tight surface that requires less "stoppering" before paint.
- Superior Adhesion: Engineered to bond aggressively to a vast array of substrates, including bare steel, aluminum, galvanized/zinc-coated surfaces, original paintwork, and GRP/Fiberglass.
- Effortless Sanding: Once cured, it sands quickly to a fine powder without clogging the paper, allowing for a seamless transition between the filler and the original panel.
