      Comments about West System #422 Barrier Coat Additive, 16oz.:

      This barrier additive is absolutely a no brainer for many marine repairs. It adds abrasion resistance and increases water resistance. It mixes in very easily and adds virtually no complications to most repairs/construction.

      I have used it to repair the keels of canoes that wear from being dragged across stream bottoms. Hands down - Works better than anything I've ever used for this application.

        I use this barrier additive in making canoe repairs. Our rental fleet of canoes takes huge abuse that wears the front of the canoes out as they are banged into rocks and scraped along the shore. This barrier coat makes a rock-hard finish that looks good, increases waterproofness and more than doubles the life of the boats. It only takes a minute to mix in and is very simple to measure out - you can't go wrong. Much better than any epoxy alone!
