This is a proprietary blend designed to improve the already excellent moisture exclusion effectiveness of WEST SYSTEM® epoxy still further. At the same time 422 Barrier Coat Additive increases the abrasion resistance and this combination makes it an excellent additive to use in order to prevent gelcoat blistering on boats. It's used simply by adding 20-25% by weight to the mixed epoxy.
