Boat Life

<h3>About BoatLIFE</h3><p><strong>BoatLIFE</strong> has been a cornerstone of the marine maintenance industry for over 65 years, earning a reputation as one of the most trusted names on the water. Founded in 1959 and proudly manufactured in the USA, the brand traces its origins to the pioneering work of Edwin Kehrt, a former U.S. Army Corps of Engineers captain whose introduction of purpose-built marine caulking and sealant compounds helped transform how boaters approach hull integrity and long-term care.</p><p>What sets BoatLIFE apart is a simple but enduring philosophy: every product in their lineup should be engineered specifically for the demands of the marine environment — not adapted from general-purpose formulas. Saltwater exposure, UV radiation, fuel contact, and constant immersion require performance standards that go well beyond what household maintenance products can deliver. BoatLIFE has built its entire catalog around meeting those standards.</p><h3>A Complete Marine Maintenance System</h3><p>At the heart of the BoatLIFE lineup is their legendary range of <a href="/7264-boat-life-caulks-sealants-201788">marine caulks and sealants</a>. The flagship Life-Calk&reg; polysulfide sealant has become an industry benchmark — a permanently flexible, waterproof compound that bonds to fiberglass, wood, metal, and glass, and can even be applied underwater for emergency repairs. Alongside it, BoatLIFE offers silicone rubber sealants, polyurethane adhesive/sealers, and teak deck sealants, giving boaters a purpose-matched solution for every sealing task above or below the waterline.</p><p>Beyond sealants, BoatLIFE produces a comprehensive suite of boat cleaners, waxes, rubbing compounds, polishes, and restoration solutions. Their Boat Cleaner features an environmentally safe, phosphate-free, biodegradable formula that lifts grime without stripping protective wax from fiberglass surfaces — a thoughtful detail that reflects the brand&apos;s understanding of how products interact throughout a complete maintenance routine. Their Life Wax line protects hull gelcoat from UV damage while delivering a deep, lasting shine, and the Teak Brite&reg; series of powder cleaners and brighteners addresses the specific needs of teak decks, swim platforms, and wood trim without damaging soft wood grain.</p><h3>Why Boaters Trust BoatLIFE</h3><p>For over six decades, BoatLIFE has refined its formulas based on real-world feedback from recreational boaters, professional captains, and marine tradespeople. Their commitment to American manufacturing means tighter quality control and formulations that reflect the conditions found in both coastal saltwater environments and freshwater lakes. Whether you&apos;re rebedding deck hardware, sealing thru-hull fittings, restoring oxidized gelcoat, or cleaning a live well, there&apos;s a BoatLIFE product engineered for the task.</p><p>The brand&apos;s in-house team of technical experts is also available to help boaters choose the right product for specific applications — a level of support that reflects genuine expertise rather than generic customer service. For anyone serious about maintaining their vessel&apos;s condition and longevity, BoatLIFE represents a time-tested, all-American solution built from the waterline up.</p>

I hope the part fits my car

This is our second order from Autoplicity. The first one didn't go so well due to a mix up with the Sparco seat pricing. Though I was starting to question our decision to order from them after several emails and phone calls and online chats, they came through in the end. These guys earned our second order by honoring the price they had listed and then calling to follow up when our race seat was shipped. Since this group was able turn our bad experience into a positive one we made our second order and, so far, it looks like they are again getting us what we want at the best price we can find. We are happy to recommend Autoplicty and plan on using them for future orders. There is one specific thing we would recommend, change the quality and volume of the hold music on the 800 #. It sounded like we were calling a 1970's van with a blown Jensen stereo turned all the way up,...

Was quick and easy

Love them!!! They send E-Mail conformation when order is placed and tracking number when shiped.
