LAUCO Ultra Gold, which is a super smooth formula, is different from other products in the auto repair market with its specific design intended to treat minor to moderate dents and scratches on various surfaces, including metal (aluminum, steel, zinc and galvanized surfaces), and fiberglass.
With Super Fill, you can say goodbye to shrinkage issues often encountered with other body fillers. Its advanced formulation ensures minimal shrinkage, resulting in a durable and long-lasting repair. This feature is particularly important for achieving a seamless and professional-looking finish on automotive surfaces.
Super Fill exhibits excellent adhesion properties, making it suitable for direct-to-metal (DTM) applications. This means that you can apply the filler directly to the metal surface without the need for a separate primer, saving both time and money in the repair process. The reliable adhesion of Super Fill ensures a strong bond between the filler and the metal, providing a solid foundation for a flawless finish.
The vacuum processed manufacturing of SuperFill significantly reduces the occurrence of pinholes, ensuring a smooth and blemish-free surface. Pinholes can be a common problem in body fillers, but with SuperFill's vacuum processed formulation, you can achieve a more professional and polished result. This feature saves time by minimizing the need for additional refinishing work.
SuperFill boasts a clog-free formula, which means that it remains easy to work with throughout the application process. This feature ensures a smooth and consistent application, reducing the likelihood of any interruptions or delays. Additionally, SuperFill is ready to sand in just 20 minutes, allowing for efficient workflow and faster turnaround times. Starting with an 80-grit sandpaper and finishing with 180-grit ensures optimal results and a refined surface ready for painting or further finishing.
