Corrosion Block

H&M Marine Corrosion Block is a proven anti-corrosive agent, frees frozen metal parts, protects electrical systems and electronics from saltwater corrosion. Provides a thin protective film that is not sticky nor will it attract dirt and moisture.

In the marine environment, corrosion is an ever-present foe. The process of corrosion is greatly inhibited by not only the environment but also smart preventative maintenance. Moisture, high temperatures (ie tropical temps), and salt are the prime forces behind metal corrosion on your boat. Use Corrosion Block to isolate moisture and stop the process.

Trouble free electronics offshore.


I have installed electronics into Sport Fishing boats on the Gulf coast for years. I use Corrision Block on all electronial terminals and connections I make and have not had any problems with saltwater corrosion on my any of my work. These boats stay wet when offshore and the electronics and lights keep working. I am now getting new boats to treat before they go out.

Awesome lubricate... try everything over


Awesome lubricate... tried everything over a ten period and nothing even comes close. Was replacing steering cable from salt water every three years, not mention getting the cable to become unsiezed. Highly recommended on moving parts and salt water.
