Description
SYSTEM THREE Glass Microspheres 4.73L (5Qt) – 3145S47.
System Three Glass Microspheres are ultra-light, hollow glass bubbles used as a low-density filler for epoxy systems. Mix into resin/hardener to create a smooth, easily sanded fairing compound ideal for filling, fairing, and contouring hulls, decks, and composite parts. The off-white blend spreads cleanly, reduces weight and shrink, and sands to a fine finish before priming and painting. Supplied in a generous 4.73 L (5 quart) container for shop or yard use.
