WEST SYSTEM 410 Microlight
WEST SYSTEM® 410 Microlight® is the ideal low-density filler for creating a light, easily-worked fairing compound especially suited for fairing large areas. Microlight mixes with greater ease than WEST SYSTEM 407 Low-Density Filler or microballoons and is approximately 30% easier to sand. It feathers to a fine edge and is also more economical for large fairing jobs. WEST SYSTEM 410 is not recommended for use under dark paint or other surfaces subject to high temperatures. It cures to a tan colour.
