Corrosion Block

Corrosion Block is a high performance anti corrosion treatment designed to protect marine metals, wiring, and components exposed to harsh saltwater environments. Its advanced formula penetrates, lubricates, and shields against rust and electrical failure without damaging plastic or rubber materials. Corrosion Block's active ingredients aren't a single chemical but rely on polar bonding chemistry with synthetic additives that penetrate corrosion cells, displace moisture (like saltwater), and leave behind a thin, hydrophobic film to stop corrosion, acting like an "off switch" for rust. It's a clean, non-greasy formula free of waxes, silicone, or Teflon, allowing it to protect electronics while lubricating and preventing further corrosion. Freeport Marine Supply carries Corrosion Block to help boaters extend the life of their onboard systems and equipment.
