West System Filler 422 Barrier Coat Additive - 473 mL
Full Product Details
While WEST SYSTEM® Epoxy creates an excellent moisture barrier by itself, 422 Barrier Coat Additive is a proprietary blend designed to improve cured epoxy’s moisture exclusion effectiveness further. 422 is used as a barrier coating additive to help prevent gelcoat blistering in polyester fiberglass boats. 422 also increases the epoxy’s abrasion resistance. Add to any mixed WEST SYSTEM 105/200 Series Hardener combination.
