West System 105B Epoxy Resin Bundle with 206B Hardener - Reliable

In this review the West System 105B Epoxy Resin Bundle with 206B Slow Hardener is evaluated for boatbuilders, woodworkers, and DIYers who need a reliable, measured epoxy system. The package combines a large 105B resin can, a 206B slow hardener, and a 3-pack of 300 mini pumps that make metering fast and consistent; the single biggest reason to buy is the ease of measurement and mixing provided by the pump set, which reduces waste and uncertainty when compared to free-pouring. The reviewer found the kit well suited to multi-step projects where working time and accurate ratios matter.

Key Features

• Premeasured pump system: The included 300 mini pumps give repeatable dispensing so users get consistent resin to hardener ratios without manual measuring each time.
• Large resin volume: The 105B resin supply (126.6 fl oz) covers multiple repairs or lamination sessions before needing replacement.
• Slow curing hardener: The 206B slow epoxy hardener provides longer working time useful for large laminations or complex assemblies.
• Made in the United States: The product is manufactured in the United States, appealing to buyers prioritizing domestic production.
• Accessory compatibility: The bundle includes roller covers and pump set items that integrate into common epoxy workflows for easier application and cleanup.

Who It's For

This bundle is aimed at experienced hobbyists, marine repair professionals, and woodworkers who need a reliable supply of epoxy and a controlled dispensing method for multiple projects. The long pot life of the slow hardener suits larger laminations or hot-shop environments where extended open time prevents premature curing.

Less experienced users who want an instant, ready-to-mix small kit may find the quantities and working time excessive, and shoppers on a strict budget should compare unit prices since some buyers report the kit is pricier than basic alternatives.

Pros & Cons

• Accurate metering pumps simplify mixing and reduce waste for repeat jobs.
• Large resin volume supports multiple repairs or lamination sessions without frequent reordering.
• Slow hardener gives longer working time for larger or complex assemblies.

Cons

• Some buyers report occasional hardener can leakage, so careful handling and storage are required.
