TotalBoat TotalFair Epoxy Fairing Compound Gallon Kit — 1:1 Mix, Sandable Marine Filler

TotalBoat TotalFair is a lightweight, two-part marine epoxy fairing compound designed to fill, shape, and fair dents, gouges, and seams on boats and other vehicles. TotalFair combines strong adhesion with a forgiving level of flex so repairs stay intact on hulls, decks, keels, topsides and more. The kit mixes 1:1 (by volume) — when the blue and yellow components are blended they turn green — and cures to a smooth, sandable surface that resists water. It works above and below the waterline on fiberglass, aluminum, steel, wood and cast iron, and comes in a gallon kit for larger jobs or multiple repairs.

How long does TotalFair take to cure and when can I sand it?

At 80°F (27°C) TotalFair reaches a sandable hardness in roughly 3–4 hours, allowing you to shape and feather quickly on the same day. Cooler temperatures slow the cure, so plan for extended cure times in cold conditions and store the kit between 60–90°F for best performance.

• Typical sandable time: about 3–4 hours at 80°F.
• Longer cure in lower temperatures — allow extra time before sanding.
• Store components between 60–90°F to preserve pot life and mixing behavior.

Which materials and areas can I use this fairing compound on?

TotalFair bonds to a wide range of marine and vehicle substrates, making it suitable for fiberglass hulls, aluminum hulls, steel, wood and even cast iron patching. Use it for fairing large surfaces, filling dings and gouges, or building up areas that need shaping prior to primer and paint.

• Suitable above and below the waterline on fiberglass, metal and wood.
• Works for boats, canoes, RVs, cars and motorcycles.
• Not a substitute for gelcoat — use epoxy primer or barrier coat before gelcoat over cured TotalFair.

What is the mixing and application process?

Mix equal parts by volume of the blue and yellow cartridges until the color is uniform green; hand-mix for 3–5 minutes to ensure full blending. The compound has a thick, creamy consistency that holds on vertical and overhead surfaces, and it sands to a pinhole-free finish once cured.

• Mix ratio: 1:1 by volume — mix until green throughout (3–5 minutes).
• Apply in layers for deep repairs — follow a 6:1 width-to-depth guideline per pass.
• Wear gloves when mixing and a respirator when sanding cured material.

How does TotalFair compare to other fairing products and what are key limitations?

TotalFair provides higher strength and better waterproofing than many polyester or vinylester fairing compounds, and it is comparable to premium two-part epoxy fillers from other marine brands. However, gelcoat will not cure if applied directly over cured TotalFair — an epoxy primer or barrier coat must be used first.

• Stronger and more waterproof than polyester/vinylester fairing compounds.
• Comparable to other two-part epoxy fillers like Interlux, Awlgrip, and System Three.
• Do not apply gelcoat directly; use TotalBoat epoxy primer or TotalProtect barrier coat first.

Who is this for? TotalBoat TotalFair is aimed at boat owners, repair professionals and DIYers who need a dependable, easy-to-mix epoxy fairing compound for medium- to large-scale repairs. It suits anyone repairing hulls, decks or gear on boats, as well as those fixing dents on cars, motorcycles or RVs who require a waterproof, sandable filler that resists sagging on vertical surfaces. If you need a made-in-USA, marine-grade epoxy that sands smooth and bonds well to multiple substrates, this gallon kit provides material for several repairs and larger fairing projects.
