<h3>About Star Brite</h3><p><strong>Star Brite</strong> has been one of the marine industry&apos;s most trusted names since its founding in 1973. <a href="/5899-starbrite">Star Brite</a> got its start with a single automotive polish product that quickly earned a loyal following — famously demonstrated in television commercials that transformed neglected junkyard vehicles into gleaming showpieces. By the mid-1980s, the brand recognized the enormous potential of the boat care market and shifted its focus toward the unique and demanding challenges of the marine environment, eventually becoming a leading manufacturer in that space.</p><p>Today, <a href="/5899-starbrite">Star Brite</a> produces a comprehensive range of marine maintenance and care products spanning hull cleaners, waxes, polishes, teak finishes, canvas protectants, fuel additives, motor oils, and much more. What sets Star Brite apart is the philosophy behind its development process: the company is run by avid boaters who test every product on their own vessels, ensuring that only the latest technology and highest-quality ingredients make it to market. The result is a lineup built to perform in real-world conditions — not just on paper.</p><p>Star Brite products are formulated using advanced materials such as nano-polymers, chelating agents, and enzymes, and the brand places a strong emphasis on environmental responsibility. Wherever possible, formulas are made to be biodegradable and safe for use around sensitive marine ecosystems — a commitment that resonates strongly with today&apos;s conscientious boaters. Every product must pass rigorous internal testing before it earns the Star Brite name.</p><p>The brand&apos;s <a href="/5899-starbrite-specialty-cleaners-200984">Specialty Cleaners</a> represent the heart of the lineup, addressing everything from stubborn waterline stains and mildew to hull discoloration and non-skid deck grime. For boat owners looking to restore and protect metal surfaces, Star Brite&apos;s <a href="/5899-starbrite-metal-cleaners-polishes-200672">Metal Cleaners &amp; Polishes</a> deliver impressive results on aluminum, stainless steel, and chrome alike. Topside fabrics and bimini tops get their own dedicated treatment through the brand&apos;s <a href="/5899-starbrite-canvas-fabric-cleaners-protectants-waterproofing-200234">Canvas &amp; Fabric Cleaners, Protectants &amp; Waterproofing</a> products, which create durable water-repellent barriers against sun, salt, and moisture.</p><p>Teak — a hallmark of classic and quality boat construction — demands specialized care, and Star Brite&apos;s <a href="/5899-starbrite-teak-products-201056">Teak Products</a> include cleaners, brighteners, and oils designed to preserve the natural beauty of this prized wood. Rounding out the range, Star Brite&apos;s <a href="/5899-starbrite-fuel-additive-12140">Fuel Additives</a> help keep marine engines running cleanly and efficiently through enzyme treatments, stabilizers, and performance-enhancing formulas.</p><p>With a state-of-the-art manufacturing and distribution facility that supplies products to virtually every country on the globe, Star Brite continues to set the standard for what marine care products can and should be.</p>

Product Details

3M Marine Adhesive Sealant 4000 UV is a one-component, medium-strength, moisture-curing, gap-filling sealant that cures to form a firm, flexible and waterproof seal on aluminum, wood, gel coat and fiberglass, making it well-suited for marine applications above or below the waterline. This sealant is formulated for color stability and UV resistance, making it especially suitable for areas exposed to the sun and wherever flexibility is important.

Key Features:

  • Becomes tack-free in as little as 22 minutes and typically cures in 24 hours
  • Medium-strength adhesive allows for disassembly of boat parts without damage after long-term use
  • Immediately paintable after curing
  • Applies right from the container with no mixing required
  • Dissipates stress caused by vibration and shock, won't crack under dynamic force, and resists salt, wind, weather and temperature extremes
  • Compatible with ABS, aluminum, nylon, PVC, metal and wood materials

This versatile marine sealant bonds portholes, deck fittings, rub rails, screw holes, and stanchion supports while still allowing disassembly. Great for cosmetic seals over permanent adhesive material.
