What Is Epoxy Resin and Why Does It Matter?

Frequently asked questions

What is the main difference between Hawk Epoxy and West System epoxy?

Hawk Epoxy leans toward versatility and finish: it offers more customizable curing speeds across multiple hardeners, a clear high-gloss cured surface, and strong adhesion to wood, fiberglass, and metal. West System leans toward proven structural performance, with decades of reliability, exceptional bonding, and a deep range of compatible fillers and additives. Pick Hawk for clarity and flexible cure, West System for structural repairs.

Which epoxy is better for a structural repair on my boat?

For structural repairs, laminating, and building composite boats, West System is the stronger fit. It is the time-tested marine standard with exceptional structural bonding and a wide lineup of fillers and additives for gap-filling and fairing, backed by detailed application guides. Hawk handles structural bonding well too, but West System's track record and additive range make it the safer default for load-bearing work.

Why would I choose Hawk Epoxy over West System for a brightwork or clear finish?

Choose Hawk when clarity and finish quality matter. It cures to a clear, high-gloss surface and offers customizable curing speeds through multiple hardener options, so you can dial in open time for the job. Combined with excellent adhesion to wood and fiberglass, that makes it well suited to lamination and bonding where you want the resin to look as good as it holds.

Is it worth keeping both Hawk and West System epoxy in the shop?

For many builders and serious DIYers, yes. The two systems answer different needs: Hawk for customizable cure speed, high clarity, and multi-surface adhesion, West System for structural strength and its broad filler and additive range. Stocking both lets you grab the clarity-first system for finish and lamination, then switch to the structural standard for transoms, bonding, and gap-filling as the work demands.

Are there any downsides to West System epoxy I should know about?

Two to plan around. West System hardeners cure slower than some brands, so factor in longer wait times before sanding or recoating. And if a layup overcures, it can be difficult to sand, so do not let it sit longer than needed before fairing. Hawk's tradeoffs are different: it runs a bit pricier and demands precise mixing for best performance.
