U-POL S2025 is a high-solids (HS) 2K polyester primer filler designed for professional automotive refinishing. This black version is an essential tool for the modern bodyshop, serving as the perfect undercoat for dark topcoats, deep blacks, and "effect" colors. By using a black foundation, you improve color depth and significantly reduce the amount of basecoat required to achieve full opacity.
Key Performance Features:
- 4-in-1 Versatility: Depending on the thinning ratio, it can be used as a high-build filler, a primer-surfacer, a primer-sealer, or for wet-on-wet application.
- Exceptional Filling Power: Highly effective at filling deep sanding scratches and minor surface irregularities without the risk of solvent entrapment or shrinkage.
- Easy Sanding: Dries to a smooth, dense finish that sands effortlessly (wet or dry) to a fine feather-edge, extending the life of your abrasives.
- Excellent Hold-out: Prevents topcoat "sink-back," ensuring the final gloss level remains consistent and brilliant long after the job is finished.
- Undercoat Advantage: Ideal for use under dark grays, blacks, and dark blues; it masks repairs more effectively than traditional grey primers.
