Easy-Blend Cream Hardener

BPO (benzoyl peroxide) is a peroxide used for curing amine accelerated polyester resins and fillers. It leads to rapid hardening and de-molding, even at low temperatures. It is used with our #4100 and our #4116 fairing and filling compounds. Each kit ships with white hardener, but you can select Black for use as a mix indicator, if desired.

BPO is sold separately in both Black and White, as well.

  • Available in 2 sizes - 1 oz. and 4 oz.
