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.

Product if fine; tube could be more durable

Most of the time I wish the mixture wouldn't set up quite so fast, so it would be easier to use on larger areas, but that just seems to be the nature of the product, no matter what company makes it.
The thing I really dislike about this is that the tube seems to fail way before using all the hardener. You have to knead the tube before using the BPO because it separates between uses. While kneading I had a tube fail at the point where the body of the tube turns toward the threaded opening, and I had a tube fail at the crimp. Each time I ended up with black fingers and the rest of the hardener in the tube was wasted. In fact, that's why I bought the tube that led to this review; the tube failed at the crimp.
