How to Prevent Pitting Corrosion on Boat Lights

In bodies of saltwater, boat lights are exposed to corrosion on a regular basis. However, there are different types of corrosion that one must know about in order to address such issues effectively. Pitting corrosion is considered to be one of the most devastating forms of damage in marine environments. This type of wear and tear is localized, which can be an indirect cause of premature failure for lights.

Identifying Pitting Corrosion

Pitting corrosion usually occurs on metallic surfaces that are exposed to highly corrosive agents. Furthermore, rough surfaces are more prone to this type of damage, compared to smooth surfaces. This is because water and chemicals tend to pool in uneven parts of the luminary, forcing chemical reactions to take place when left unaddressed.

Sections of equipment where dirt can deposit is a great place to start when inspecting boat lights for pitting corrosion. Any unsealed sections of the unit may also be prone to breakdown. Because of this, it is important not to use absorbent materials to protect boat lights.

Best Practices

After identifying the issue, individuals should move forward with repair to prevent further damage. There are some best practices to factor in to ensure maintenance and reduce the effects of pitting corrosion. One of these includes the application of resistant coatings. This solution may also be effective in decreasing UV damage and improving the sturdy nature of the material.

Washing and drying the surface of the boat light is another useful method for preventing corrosion. Drying is often overlooked but should be equally prioritized, as pockets of water can cause unwanted chemicals to pool on the surface (resulting in corrosion). Lastly, selecting the right type of material during purchase is recommended for boat lights that will be used in the water for long periods of time.
