Forespar Corrosion Control Product

Forespar Corrosion Control: Marine-Grade Protection Built for the Sea

Forespar has been engineering solutions for the marine world since 1966, and their corrosion control products stand as some of the most trusted in the industry. Anyone who has spent time on the water knows that corrosion is not just a nuisance — it is one of the most relentless forces a boat owner faces. Salt air, constant moisture, dissimilar metals, and galvanic reactions conspire to degrade fittings, fasteners, and electrical connections season after season. Forespar's corrosion control lineup was designed specifically to combat these challenges with science-backed, marine-grade formulations.

LanoCote®: The Flagship Corrosion Fighter

At the heart of Forespar's corrosion control category is LanoCote®, a product that has earned a devoted following among sailors and powerboaters alike. Forespar LanoCote is a heavy-duty rust and corrosion protection solution formulated with natural lanolin to provide superior, long-lasting defense against moisture, salt, and harsh marine environments. What sets it apart from petroleum-based competitors is its natural foundation: it is a combination of non-toxic corrosion inhibitors and spreading and conditioning agents that delivers broad-spectrum, long-term protection against rust, acids, alkalis, and salts — and it is lanolin-based.

One of LanoCote's most practical qualities is its durability in active marine conditions. It will not dry, evaporate, or wash off — a critical trait for hardware regularly submerged or exposed to spray. LanoCote works on five basic principles: it displaces water, absorbs corrosion, forms a moisture barrier, penetrates surfaces, and provides high lubricity. This multi-action approach means it does more than just coat metal — it actively interrupts the corrosion cycle.

One of the most practical applications for LanoCote is preventing thread seizure. Formulated to withstand saltwater marine conditions, LanoCote is particularly useful in preventing thread seizure due to all types of corrosion on boats and machinery, and applied during assembly, it will greatly assist in easy dismantling years later. It also addresses galvanic corrosion: LanoCote combats galvanization where dissimilar metals are fastened together, such as stainless steel fittings on alloy masts. LanoCote is available in multiple formats — paste jars and spray bottles — making it easy to apply in tight spaces or on large surface areas.

MareLube TEF45: Advanced PTFE Corrosion Inhibition

For applications demanding even greater performance, Forespar offers MareLube TEF45. MareLube TEF45 is a premium high-load, anti-seize, and corrosion inhibitor developed to exceed the demanding needs of marine professionals, boat builders, and private owners. It lubricates and mechanically plates metal surfaces with a PTFE film to provide maximum protection against friction, wear, and corrosion — and is totally waterproof and chemical-resistant, with no volatile solvents, silicones, or petroleum to evaporate, and it will not cold flow or dry out. It is particularly well-suited for valve maintenance, electrical connections, and high-load fastener applications aboard both sail and power vessels.
