<h3>About WEST SYSTEM Epoxy</h3><p>Since 1969, <strong>WEST SYSTEM</strong> has been the benchmark for marine-grade epoxy technology. Founded and headquartered in Bay City, Michigan, the brand built its reputation in the demanding world of boat building and boat repair — environments where structural integrity and long-term moisture resistance are non-negotiable. Decades later, WEST SYSTEM remains the go-to choice for professional boatbuilders, marine repair technicians, and dedicated DIYers around the world.</p><p>At the heart of the brand is the legendary <strong>105 System</strong> — a modular, field-proven approach to epoxy that gives users precise control over every aspect of a repair or build. The system centers on WEST SYSTEM Epoxy Products, which pair the 105 Epoxy Resin with a selection of hardeners, each engineered for different working conditions and cure speeds. Whether you need a fast-setting compound for a quick on-the-water fix or a slow-curing formulation for a complex laminating job in warm weather, there is a hardener designed for the task.</p><p><a href="/7644-west-systems-epoxy-adhesives-200378">WEST SYSTEM Epoxy Adhesives</a> take that same foundation and extend it into high-strength structural bonding. These formulations are compatible with wood, fiberglass, Kevlar, carbon fiber, metals, and ceramics — making them equally at home in a marine boatyard, a woodworking shop, or a composite fabrication facility. WEST SYSTEM epoxy forms strong, load-bearing bonds that often exceed the strength of the surrounding material , which is why builders trust it for everything from hull construction to bulkhead installation.</p><p>Rounding out the system, <a href="/200404-fillers-west-systems-7644">WEST SYSTEM Fillers</a> allow users to fine-tune the physical characteristics of a mixed epoxy batch. Users can adjust the epoxy with one of six WEST SYSTEM fillers, or add one of several additives to create specific coating properties. Options range from low-density fairing compounds ideal for creating smooth, sandable surfaces, to high-density microfiber blends engineered for structural glue joints and filleting work.</p><h3>Why WEST SYSTEM Stands Apart</h3><ul style="list-style:disc"><li><strong>Modular versatility:</strong> WEST SYSTEM Epoxy products make up a versatile epoxy system that can be used for everything from basic, long-lasting, marine epoxy repairs to the construction of high-performance composites. </li><li><strong>Moisture resistance:</strong> Designed to create a protective barrier, WEST SYSTEM epoxy prevents water infiltration, ensuring long-term durability in marine environments. </li><li><strong>Broad material compatibility:</strong> WEST SYSTEM marine epoxy is compatible with various materials, including fiberglass, Kevlar, and carbon fiber, for superior structural integrity. </li><li><strong>User-focused design:</strong> WEST SYSTEM 105 Epoxy Resin, Hardeners, Fillers, Additives, and Materials are designed and developed with the end-user in mind. </li></ul><p>Whether you are restoring a classic wooden sailboat, cold-molding a new hull, patching a delaminating deck, or fabricating a custom composite component, WEST SYSTEM provides the engineered materials and the technical guidance to get the job done right the first time.</p>

Product Details

West System 655-8 G/Flex Thickened Epoxy is a toughened, versatile liquid epoxy adhesive designed for permanent waterproof bonding applications. This professional-grade epoxy excels at bonding challenging materials including fiberglass, ceramics, metals, plastics, and even damp or difficult-to-bond woods.

Key Features:

  • Modulus of elasticity of 150,000 PSI for enhanced flexibility compared to standard epoxies and polyester resins
  • Waterproof formula creates permanent, durable bonds in wet or marine environments
  • Toughened formulation resists impact and stress
  • Bonds to a wide variety of substrates including dissimilar materials
  • Works effectively on damp surfaces where traditional epoxies fail
  • 8 oz. kit includes both resin and hardener components

G/Flex's unique elasticity makes it ideal for bonding materials with different expansion and contraction rates, reducing the likelihood of joint failure. The thickened consistency provides excellent gap-filling properties and prevents runoff on vertical surfaces. Perfect for marine repairs, automotive applications, composite fabrication, and general-purpose bonding where flexibility and strength are required.

I am a little unsure that this is for the 6 ft bed.

So far so good, great price.

Excellent price.

Will use Autoplicity in the future. Just dont fully belive the 24hour shipping. I ordered 2 parts that where listed as in stock and it still took 3 days to ship. When I called customer service about my order agents where rude and stated there shipping is based upon 24 "buisness" hours.

good

I ordered a part that did not fit, returned no hassles. I just ordered two items and hope they look great.

Good very good

I like how I could use my amazon account to check out. Made it go very fast

Easy store to navigate through and had all the info.

Easy to enough to navigate website. Wish it was just a bit more organized when it comes to vehicle specific items.

I received my ARP head studs as described and on time with zero problems, and cheaper than anywhere else.Will use again!!!

Great price on my short ram air intake... Actually, best I could find on the Internet. Product shipped the day after the order. Haven't had any problems so far, but it was only shipped just today.

Received the spider gears a day late due to weather conditions. Overall great!
