3M Company 928 Red Cream Hardener 2.75 Oz

Product Description

The 3M COMPANY 928 is a red cream hardener designed for use with white auto body filler. When mixed, the red colorant blends with the white filler, giving technicians a clear visual indicator that the hardener is fully incorporated. This eliminates guesswork during mixing and helps prevent improperly catalyzed filler from being applied to a repair panel. At 2.75 oz per tube, the 928 is sized for professional body shop use and provides a consistent cure when used at the correct mix ratio. Automotive body technicians and collision repair professionals are the primary installers of this product.

The 928 is used in automotive collision repair and refinishing applications wherever cream hardener is required to catalyze polyester-based body filler. It is applied in body shop environments on passenger vehicles during panel straightening, dent repair, and surface preparation before priming. The 2.75 oz size suits standard repair jobs and is sold in packages of 6 units, making it practical for shop inventory management.

Installation Notes

This product is applied by automotive body technicians in collision repair environments. Dispense the appropriate amount of body filler onto a clean mixing board, then add hardener and mix thoroughly until the color is uniform before applying. Work in a well-ventilated area and follow the filler manufacturer's recommended hardener-to-filler ratio. Avoid over-catalyzing, as excess hardener can cause pinholing or accelerated cure that reduces working time.
