WEST SYSTEM 105A Epoxy Resin Bundle with 207SB Clear Hardener - Clear

In this review the WEST SYSTEM 105A Epoxy Resin bundle is presented as a practical all-in-one kit for woodworkers, boat builders, and repairers who need a reliably clear coating and predictable cures. The bundle pairs a 32 fl oz can of 105A resin with a 10.6 fl oz 207SB extra clear hardener and calibrated 300 mini pumps, making it easy to measure the correct 3:1 mix. The single biggest reason to buy is its clarity and low-viscosity flow that wets out wood and fabrics cleanly, producing a natural, moisture-resistant finish with minimal odor.

Key Features

• Convenient bundle: Includes a full 32 fl oz can of 105A resin, a 10.6 fl oz can of 207SB extra clear hardener and a set of calibrated 300 mini pumps so you have the core components for coating or bonding projects in one purchase.
• Water-clear coating: The 207SB special clear hardener cures to an exceptionally clear, moisture-resistant finish, ideal for natural wood topcoats and clear fiberglass layups.
• Correct metering: Calibrated mini pumps deliver the intended 3:1 resin to hardener ratio in matched strokes, reducing measurement errors and waste for small batch mixing.
• Low viscosity resin: 105A is a clear, low-viscosity epoxy that wets out wood fiber and reinforcing fabrics without fisheyeing, improving adhesion and surface finish.
• Blush-free performance: 207SB resists humidity-induced clouding so thin film applications roll out smoothly and require less sanding before final finish coats.
• Friendly handling: No solvent odor and a relatively high flash point make this epoxy less harsh to use than styrenated systems in typical workshop conditions.

Who It's For

This bundle is best for hobbyists and professionals focused on boat repair, strip kayak and canoe construction, furniture finishing, or any project needing a clear, durable epoxy coating. The included pumps and the 3:1 mix ratio are particularly helpful for users who want quick, repeatable small-batch mixes without weighing containers.

Those working at very low temperatures or needing long working times for large laminations should look elsewhere for a slower hardener or larger kit sizes, since pot life is limited and the bundle covers modest project volumes rather than large production runs.

Pros & Cons

Pros

• Produces a glass-clear, moisture-resistant finish that highlights natural wood grain and gives good physical properties.
• Mini pumps simplify accurate dosing and reduce measuring mistakes for routine mixes.
• Low-viscosity resin wets out fabrics and wood easily, reducing trapped air and fisheyeing.

Cons

• Some customers report mixed experiences with pump delivery and occasional missing pumps, so inspect the kit on arrival.
• Shorter pot life at 72F (20 to 26 minutes) requires quick working and planning for larger pours.

Specifications

Our Verdict

The WEST SYSTEM 105A bundle is a smart choice for woodworkers and small-scale marine repair where a clear, durable epoxy coat is required and repeatable measuring matters. It represents good value for projects that fit the kit volume and working time, offering a blush-free clear hardener and pumps that speed up routine mixing. Inspect pump condition on arrival, but for most hobbyists this kit streamlines clear coating and bonding tasks without the odor and handling issues of solvent-based alternatives.

Frequently Asked Questions

Can the pumps be used to mix the correct ratio?
Yes, the calibrated mini pumps are designed to deliver the 3:1 resin to hardener ratio with matched strokes, producing the correct mixed volume per stroke.

Will the finish stay clear in humid conditions?
Yes, the 207SB extra clear hardener is formulated to be blush-free and resist clouding in humid environments when used as directed.

How long do you have to work with a mixed batch?
At 72F (22C) expect a pot life of about 20 to 26 minutes, so plan small batches or work quickly for larger pours.
