Use with Our Many Lines of Auto Body Filler
3M™ Dynatron™ White 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.
The Best Choice When a Neutral Color is Preferred
Our white cream hardener is ideal for situations in which a neutral color is preferred. The white color allows for keeping the mixture the natural color of the product being used.
Formulated to Reduce Chances of Pinholes
Our cream hardener is formulated and packaged under temperature-controlled conditions to ensure freshness and maximum performance. 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.
