we've build a rooftop rail and used the deck surfacing boards trex. hit it a few times and chipped/torn some of the plastic coating off the edges on the outside. we've ripped off the hanging off plastic and it shows the composite of the board. To fill up the hole we're thinking of using the Liquid Force Ding Repair Kit since they are such small holes. Would that repair stuff work well? or would a two part epoxy be better?
