West System Products
What Are West System Products?
West System products form one of the most trusted and comprehensive epoxy systems available for marine and RV maintenance. At the heart of the lineup is a two-part epoxy system — a base resin combined with a choice of hardeners — that cures at room temperature to create a high-strength, moisture-resistant bond. Whether you're patching a fiberglass hull, rebuilding rotted wood on an RV, reinforcing a deck, or sealing structural joints, these products are engineered to deliver professional-grade results in demanding environments.
Epoxy Resins & Hardeners
The foundation of the system is the base epoxy resin, a clear, low-viscosity liquid that bonds to wood, fiberglass, reinforcing fabrics, foam, and many metals. What sets this system apart from off-the-shelf adhesives is the selection of hardeners that allow you to tailor cure speed to your specific project and working conditions. Fast hardeners are ideal for cooler temperatures and quick jobs, while slow and extra-slow hardeners provide the extended working time needed for large laminations or warm, humid conditions. Choosing the right hardener is one of the most important decisions in any epoxy project — the wrong choice can leave you racing the clock or waiting unnecessarily.
Fillers & Additives
One of the most powerful aspects of this system is the range of compatible fillers and additives. Once the base resin and hardener are mixed, fillers can be blended in to adjust viscosity and tailor the epoxy's final characteristics for specific tasks. High-density fillers maximize bonding strength for hardware attachment and structural joints, while low-density fairing fillers create lightweight, easily-sanded fairing compounds ideal for hull shaping. Wood-toned fillers are popular for creating natural-looking fillets and glue joints on wood surfaces. Specialty additives like graphite powder can even be mixed in to create a low-friction, scuff-resistant exterior coating.
Repair Kits & Specialty Adhesives
For boaters and RV owners who want a ready-to-use solution, pre-configured repair kits bundle the right resin, hardener, and accessories for common jobs like fiberglass boat repair, aluminum boat seam sealing, and wood rot restoration. Flexible, toughened epoxy adhesive formulas — distinct from the standard rigid system — are designed to bond challenging materials like plastics, ceramics, and wet or difficult woods where a standard epoxy might fail. These specialty adhesives maintain a degree of flex after curing, making them ideal for joints that experience movement or vibration.
Metering Pumps & Application Tools
Accurate mixing is critical — altering the resin-to-hardener ratio even slightly can compromise the cured epoxy's strength and moisture resistance. Calibrated metering pumps mount directly onto resin and hardener containers to dispense the correct 5:1 ratio with every stroke, eliminating guesswork. Mixing pots, spreaders, fiberglass fabric tape, and other application accessories round out the system, giving DIYers and professionals everything they need for a clean, reliable repair from start to finish.
