A pre-blended lightweight fairing powder so you are not measuring three separate fillers into a cup on a hot day. It is our own blend of fumed silica, phenolic microballoons and 3M glass bubbles: the silica gives it body so it does not slump, the microballoons and glass bubbles keep it light and make it sand. Add epoxy, trowel, sand. Mix into mixed epoxy to a trowelable consistency, apply, then fair to a primer-ready surface. Consistent every batch. Same ratio each time, so the sanding behavior does not change between fills. For epoxy. The blend is formulated for epoxy systems. Sands easy. The lightweight component fraction is what keeps it from loading paper. Sizes: 1 quart, 1 gallon and 4 gallon. Fair it slightly proud and sand back to the surrounding surface. Pulling a fill flush with the trowel almost always leaves it low after cure.
