FIBERLAM Plus 1-10G Polyester Resin 2 Gallon Kit - Extended Tack Time

Our review of the FIBERLAM Plus Polyester Fiberglass Laminating Resin 2 gallon kit finds it well suited for professional and dedicated DIYers who need a reliable marine-grade laminating resin. The kit ships with 2 gallons of low viscosity resin plus two 2oz bottles of MEKP and a pipette, so a user can begin layups immediately; the single biggest reason to buy is the combination of marine-grade formulation and extended tack time that makes multi-layer layups and vertical laminations easier and cleaner. This review focuses on real-world handling, cure behavior, and the kit contents to help decide if it fits your shop workflow.

Key Features

• Complete 2 gallon kit: Arrives with 2 gallons of FiberLam Plus resin, 2 x 2oz MEKP bottles and a pipette so projects can start without extra purchases.
• Marine grade formulation: An Ortho-type polyester resin used by marine and RV builders, giving confidence for hull repairs and structural laminations.
• Low viscosity for wetout: Flows easily to impregnate fiberglass mat, biaxial cloth and woven fabrics for consistent wetout and fewer dry spots.
• Extended tack time: Stays tacky longer to allow layering and vertical work without premature sagging or drips during multi-ply builds.
• Cures tack free in 24-36 hrs: Designed to cure fully without wax in typical shop conditions, simplifying post-cure handling and finishing.
• Mix chart and label guidance: Mix ratio information is printed on the label and the pipette helps measure MEKP accurately for repeatable work times.

Who It's For

This resin kit is best for boat builders, RV and auto body repairers, and advanced hobbyists who need a marine-grade polyester resin with good wetting and extended tack time for multilayer laminations and vertical work. It is appropriate for repairs, new FRP parts, and general laminating where gelcoat adhesion and structural integrity are priorities.

Less suitable are casual users who want an ultra-fast cure resin for same-day finishing, or those who require a pre-waxed resin specific for fiberglass topside finishes; users needing epoxy-level adhesion or flexibility should look at epoxy systems instead.

Pros & Cons

Pros

• Includes MEKP catalyst and pipette, so the kit is ready to use out of the box.
• Marine-grade, low viscosity formula that wets fiberglass cloth and mat quickly and evenly.
• Extended tack time helps when stacking layers and performing vertical laminations.
• Cures tack free in 24-36 hours under normal shop temperatures without wax.

Cons

• Final cure time depends on temperature and MEKP amount and can be slower below 72F, so cold shops may see longer waits.
• As an ortho polyester system, it lacks the bond and flexibility characteristics of epoxy for some specialty repairs.

Our Verdict

The FIBERLAM Plus 2 gallon polyester resin kit is a practical, cost-effective choice for marine, RV, and transportation laminating where reliable wetout and longer tack time matter. It delivers ready-to-use contents and predictable cures in normal shop conditions, making it a good value for professionals and experienced DIYers; those needing faster cold-weather cures or epoxy-level performance should consider alternatives.
