Bondo 912 Liquid Hardener 11 ml
This 3M liquid hardener is formulated for use with Bondo polyester fiberglass resin and compatible resin systems. It provides the necessary catalyst for proper curing in automotive and general repair applications. The 11 ml volume suits small to medium mixing batches.
Room-temperature curing with standard mix ratios
The hardener activates at typical workshop temperatures without external heat sources. Mixing follows the resin manufacturer’s recommended ratio for consistent cross-linking. Pot life allows adequate working time before gelation begins. Clean-up uses common solvents while the material is still uncured.

Questions about this item
How do I install the 11 ml Bondo 912 liquid hardener and what step is often missed?
Measure the recommended ratio, mix thoroughly with the polyester fiberglass resin, and apply immediately; the step often missed is scraping the container sides to ensure a uniform cure.
What maintenance or replacement will the 912 liquid hardener need later?
The 11 ml bottle is single-use; once opened it cannot be resealed reliably, so replace it with a fresh unit for each new repair job.
