Re-chroming rims involves a multi-step process of stripping the old finish and applying new layers of metal plating. It's important to understand that this is a complex procedure often best left to professionals and can sometimes cost more than purchasing new rims.
The Re-Chroming Process: A Detailed Overview
The typical re-chroming process consists of these stages:
-
Inspection and Preparation:
- The rim is thoroughly inspected for any damage such as dents, cracks, or corrosion. Any necessary repairs are made before proceeding.
- The rim is then cleaned to remove dirt, grease, and any existing coatings.
-
Stripping the Old Chrome:
- The old chrome plating is removed through a chemical stripping process. This involves immersing the rim in a series of chemical baths that dissolve the existing chrome layer.
-
Metal Polishing and Buffing:
- After stripping, the rim's surface is polished and buffed to create a smooth and even base for the new plating. This step is crucial for achieving a high-quality, reflective chrome finish.
-
Copper Plating:
- A layer of copper is applied to the rim through electroplating. This copper layer acts as a base coat, filling in any imperfections and providing a smooth surface for the subsequent layers.
-
Nickel Plating (Optional but Recommended):
- A layer of nickel is applied after the copper plating. Nickel provides corrosion resistance and improves the adhesion of the final chrome layer. While optional, adding a nickel layer dramatically improves the longevity of the finish.
-
Chrome Plating:
- The final layer of chrome is applied through electroplating. This thin layer of chrome provides the bright, reflective finish that gives chrome rims their distinctive appearance.
-
Final Polishing and Cleaning:
- After chrome plating, the rim is polished and cleaned to remove any residue and enhance the shine.
Important Considerations:
- Professional Expertise: Re-chroming involves hazardous chemicals and specialized equipment. It is highly recommended to have this process done by experienced professionals to ensure safety and quality.
- Cost: The cost of re-chroming can vary depending on the size and complexity of the rim, as well as the extent of any necessary repairs. Get quotes from multiple shops before making a decision. Be aware that the price can exceed the cost of a new wheel.
- Environmental Impact: The re-chroming process produces toxic waste. Ensure the shop you choose follows proper environmental regulations and waste disposal procedures.
- Alternatives: Consider alternatives to re-chroming, such as powder coating or purchasing new rims, especially if the cost of re-chroming is prohibitive. Powder coating offers a durable and customizable finish and is often a more affordable solution.
In conclusion, re-chroming rims is a complex electroplating process. Due to the cost and safety concerns it's often recommended to consult professional services before considering a DIY method.
