Manufacturer product information. Follow the product label and current manufacturer instructions for preparation and application.

Selecting and using this filler

Primary application	Fairing and shaping cured surfaces; prioritize sandability over a structural adhesive role.
Color	Dark red/brown when cured
Base system	WEST SYSTEM 105 Resin with a compatible 200-series hardener
Curing agent	None: this is an additive, not a resin or hardener

First proportion and mix the resin and hardener correctly, then add filler to achieve the consistency required for the application. Filler does not replace hardener or change the resin-to-hardener mixing ratio. Use the manufacturer's filler guide to choose between adhesive bonding and fairing products.
