3M Bondo 913 Red Cream Hardener is a high-quality curing agent specifically designed for use with Bondo brand and other polyester body fillers, putties, and glazes. You will find that when mixed with a filler, this hardener initiates a chemical reaction that transforms the pliable paste into a durable, sandable solid in just minutes. This product feels smooth and easy to blend, featuring a vibrant red color that serves as a visual indicator to ensure you have achieved a consistent, streak-free mix. Because it is formulated for professional-grade repairs, this 0.75-ounce tube provides enough catalyst for a standard pint of filler, making it a critical component for restoring the smooth contours of automotive bodywork or home repair projects.

Additional Information
To achieve the perfect mix, you should follow the “ribbon” rule: for a golf-ball-sized amount of filler, apply a 1-inch strip of hardener across it. You should use a firm, non-porous mixing board and a plastic spreader to knead the two components together using a folding motion rather than stirring, which helps prevent trapping air bubbles in the paste. Avoid adding too much hardener, as “over-catalyzing” can cause the repair to become brittle or lead to staining that bleeds through your final paint job. It is a good practice to only mix what you can apply within three to five minutes, as the hardening process begins almost immediately once the red cream is introduced.
