West System 655-405 Filleting Blend

West System 655-405 Filleting Blend

Create clean, strong fillets and fill glue joints on wooden boat interiors with this wood-toned epoxy filler. The 655-405 Filleting Blend is formulated to mix smoothly into West System G/Flex 655 Epoxy or standard WEST SYSTEM epoxy systems, producing consistent brown fillets that blend naturally with bare wood surfaces. The improved formula reduces drag during application, so fillets lay down cleanly and require minimal sanding before finishing.

Key Features

• Wood-toned brown colour integrates naturally with unfinished wooden interiors
• Improved formula mixes easily into epoxy for smooth, consistent fillets
• Reduces sanding time after application
• Can be blended with other WEST SYSTEM fillers to adjust shade
• Ideal for glue joints, fillets, and fairing on wooden boat structures

Parts Desk Insights

Best Use Case: This filler is the go-to choice for wooden boat builders and repair technicians working on naturally-finished interiors where fillet colour matters. It excels in structural glue joints along hull planking, keel fillets, and interior framing anywhere a brown-toned fillet will be left visible or lightly varnished. Pair it with West System G/Flex 655 Epoxy for flexible bonds on wood-to-wood joints, or use it with standard WEST SYSTEM 105 resin systems for rigid structural fillets. For customers working on painted surfaces where colour is irrelevant, a lower-cost filler may suffice but for bright-finished woodwork, this is the correct product.
