View larger. How It Works Bondo Auto Body Filler consists of two compounds: a resin based filler and a hardening agent. A tube of the hardening agent is included with the container of Bondo Auto Body Filler. The consistency of both compounds is creamy, but as the hardening agent is blended together with the filler it acts as a catalyst, creating a chemical reaction which thickens the new mixture into a paste. Bondo Auto Body Filler products include directions containing simple mix ratios that make for convenient measuring out of both compounds without any waste. The compounds should be blended away from the area to be repaired on a handheld mixing palette or other maneuverable flat surface using a flat edged spreading tool (palette, spreading tool and recommended eye protection, mask and solvent resistant gloves sold separately). The result is a rapidly thickening adhesive mixture that can be spread on and will stick to correctly prepared surfaces and spaces. The mixture cures quickly, shapes in minutes and will accept as many reasonably applied applications as required to fill holes and deep scratches or dents. It is is formulated to be a non-shrinking and permanently durable material. Once completely hardened Bondo Auto Body Filler can be sanded using various grits to achieve as smooth a finish as required. The filled, area as well as the area immediately surrounding it should be covered with Bondo Glazing and Spot Putty (sold separately). Feather sanding this creates a consistent sloping surface that can then be painted with standard gray auto primer and an outer coat and clear coat finish. In addition to its uses in repairs of typical vehicle surfaces Bondo Auto Body Filler is also suitable for repairs of other surfaces including wood, steel, aluminum, fiberglass, and concrete.
