West System 407 Filler Low Density

WEST SYSTEM® 150g Filleting blend is a high-density blended filler consisting of loose chopped glass and other fillers intended for small semi-structural repairs, filling voids, or small-scale impact damage to glass fibre laminates. The finished repairs are incredibly strong, tough, and resilient.

When mixed with WEST SYSTEM epoxy at a ratio of approximately 25% by weight, the result is a thick paste that can be carefully stippled into place with a brush and can be held in place with PVC tape or peel ply to give a smooth finish to the repair. In the marine world, typical uses include deep void repair due to osmotic damage; damage to dinghy rudders and centre boards, and hard edge impact damage on small sailboats.
