Bell Hammer Gold is originally designed as an extreme pressure lubricant with anti-corrosion properties, and under normal conditions, it works to prevent rust formation.
However, there have been reports of localized rust formation under certain combined conditions.
One such cause is galvanic corrosion, which occurs at joints involving dissimilar metals.
Hinges and bolts often consist of combinations such as steel, zinc plating, and paint. These junctions are especially prone to corrosion due to potential differences between the materials.
In some cases, uneven distribution or concentration of the lubricant components—such as during evaporation—can influence these electrochemical reactions.
Although this is based on image analysis, we suspect the symptoms in this case may also be due to this mechanism.
Future Recommendations:
Given the combination of Bell Hammer Gold's formulation and the materials involved in this application, there is a high possibility that similar corrosion may recur.
We recommend cleaning the affected area with a parts cleaner to remove the rust, and then applying a silicone- or fluorine-based lubricant with strong anti-corrosion performance.
From our product line, we suggest switching to the fluorine-based H1 Bell Hammer Spray, which offers enhanced rust prevention properties.
