The single biggest reason to buy is the foolproof metering pump combination that delivers the correct 5:1 mix ratio every time, removing common measuring errors and giving consistent curing and adhesion. The kit pairs a 32 fl oz clear, low-viscosity resin with a 7 fl oz slow hardener and calibrated pumps to simplify mixing, extend working time, and improve results on fiberglass, wood, and composite repairs.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eComplete bundle:\u003c\/strong\u003e Includes one 32 fl oz can of 105A resin, one 7 fl oz can of 206A slow hardener and a matched pump set for immediate use without extra measuring tools.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eAccurate metering:\u003c\/strong\u003e Calibrated 300 Mini Pumps dispense the correct 5:1 resin to hardener ratio so mixed batches are consistent and easy to reproduce.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eExtended working time:\u003c\/strong\u003e 206A Slow Hardener is low viscosity and provides longer pot life for larger laminations or warm-shop conditions.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eStrong bonding:\u003c\/strong\u003e When blended at the specified ratio the epoxy cures to a hard solid with good adhesion to wood, fiberglass and many metals.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eSafe to work with:\u003c\/strong\u003e The formulation has no solvents or VOCs and a relatively high flash point, so it has lower odor than styrenated alternatives.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eEasy modification:\u003c\/strong\u003e The resin accepts West System fillers and additives for fairing, filleting, or coating tasks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe bundle is best suited for hobbyist and professional marine repairers, canoe and kayak builders, and general woodworkers who value precise mixing and predictable pot life.
