3M™ Cream Hardener

3M™ Cream Hardener mixes with 2-part fillers, putties and glazes to create high-quality, long-lasting repairs. This hardener is smooth and easy to mix in.

3M™ Cream Hardener is a hardening agent designed to work with our 2 part 3M™, Dynatron™ and Bondo™ fillers, putties and glazes. The creamy consistency mixes easily and quickly. Our hardener combines the best of ease of use and quality final results. The hardeners should not be used by themselves. Cream hardeners with tinted colors help you ensure consistency when mixing hardener and filler together. The color of the cream hardener will not affect curing. Mixing auto body filler with our cream hardener is an easy task. To reduce the chance of creating pinholes, avoid mixing in a circular pattern, which can force air into the mix. Mixing should be done in a back and forth wiping or folding motion.
