So what is it?

Corrosion Block is a revolutionary product that kills corrosion on contact, stops corrosion from ever coming back, and finally lubricates the area. Corrosion Block is safe to nearly all electronics. Corrosion block is a marine version of the aviation and military's ACF-50. This is a specially formulated penetrant that was created to battle the worst kind of corrosion.

It is a state-of-the-art, corrosion inhibitor / lubricant compound designed for marine use. It is a clean, clear, ultra-thin fluid compound which leaves a non-greasy atmospheric barrier to protect metals. It leaves no gummy residue, and it can be sprayed on or wiped on with a damp rag.

How is it Different?

  • Completely nonconductive
  • Lasts for 6-12 months
  • Safe to plastics and rubbers
  • Prevents and stops corrosion

The Best ROI Around

It is estimated that corrosion costs the US nearly 300 billion per year. Use Corrosion Block to protect your equipment before the damage takes place. Experts estimate that protecting your equipment now is 10x cheaper than repairing it later. As a bonus, electrical and mechanical parts will run smoother and more efficiently.

Use it Anywhere!

While formulated for marine use, Corrosion Block is great for automotives, industrial equipment, HVAC systems, and any other metal objects exposed to corrosive environments. See our Uses page to see the many ways Corrosion Block can be used.

How Does it Work?

A typical sealant traps in moisture. It works by sealing the material and slows future corrosion, but doesn't reverse the damage.


A typical sealant actually traps in the moisture.
Future corrosion is slowed, but the damage is not reversed.
This is not proper corrosion protection.

corrosion block displaces moisture

Corrosion block penetrates deep to the root of the problem, destroying existing corrosion and creating a protective barrier. The moisture is displaced to the top, where it evaporates off ! This is the best rust prevention method available.

Steps of Corrosion Protection:

First, Corrosion Block actively penetrates the corrosion on the surface of the metal, electrically isolating it from the base metal.
Second, it proceeds to displace the moisture present in the cell, bringing it to the surface where it evaporates!
Third, the cell is then filled and protected with a 40KV dielectric barrier to establish corrosion protection for at least 18 months.
