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.\n\n\u003ch3\u003eHow long does TotalFair take to cure and when can I sand it?\u003c\/h3\u003e\n\u003cp\u003eAt 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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTypical sandable time: about 3–4 hours at 80°F.\u003c\/li\u003e\n  \u003cli\u003eLonger cure in lower temperatures — allow extra time before sanding.\u003c\/li\u003e\n  \u003cli\u003eStore components between 60–90°F to preserve pot life and mixing behavior.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich materials and areas can I use this fairing compound on?\u003c\/h3\u003e\n\u003cp\u003eTotalFair 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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSuitable above and below the waterline on fiberglass, metal and wood.\u003c\/li\u003e\n  \u003cli\u003eWorks for boats, canoes, RVs, cars and motorcycles.\u003c\/li\u003e\n  \u003cli\u003eNot a substitute for gelcoat — use epoxy primer or barrier coat before gelcoat over cured TotalFair.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat is the mixing and application process?\u003c\/h3\u003e\n\u003cp\u003eMix 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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMix ratio: 1:1 by volume — mix until green throughout (3–5 minutes).\u003c\/li\u003e\n  \u003cli\u003eApply in layers for deep repairs — follow a 6:1 width-to-depth guideline per pass.\u003c\/li\u003e\n  \u003cli\u003eWear gloves when mixing and a respirator when sanding cured material.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does TotalFair compare to other fairing products and what are key limitations?\u003c\/h3\u003e\n\u003cp\u003eTotalFair 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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eStronger and more waterproof than polyester\/vinylester fairing compounds.\u003c\/li\u003e\n  \u003cli\u003eComparable to other two-part epoxy fillers like Interlux, Awlgrip, and System Three.\u003c\/li\u003e\n  \u003cli\u003eDo not apply gelcoat directly; use TotalBoat epoxy primer or TotalProtect barrier coat first.\u003c\/li\u003e\n\u003c\/ul\u003e\n\nWho is this for?\n\nTotalBoat 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.\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use TotalFair below the waterline?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
