Use with Many Lines of Car Body Filler - Bondo Cream Hardener is a hardening agent designed to work with all fillers, putties and glazes. The creamy consistency mixes easily and quickly. Our hardener combines the best of ease of use and quality final results. Formulated for Convenience - When mixed with a 2-part filler, a chemical reaction occurs which allows you to make high-quality, long-lasting repairs to metal, masonry, concrete, painted wood, bare wood, drywall and more. The resulting repair can be sanded in 15 minutes and painted in only 45 minutes. Tinted Colors Help with Consistency - Cream hardeners with tinted colors help you ensure consistency when mixing hardener and filler together. By looking at the color of the mixture, you can get an idea about whether you have too much or too little hardener. The color of the cream hardener will not affect curing. Formulated to Reduce Chances of Pinholes - Cream hardener is formulated and packaged under temperature-controlled conditions to ensure freshness and maximum performance. Mixing auto body filler and 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.
