I. Professional repair methods
1. Overall chrome removal and vacuum plating
For severely worn or corroded parts, it is necessary to remove the chrome as a whole, weld the damaged area and then re-chrome plating and fine polishing, which can restore the original brightness and enhance corrosion resistance.
Vacuum plating technology is suitable for complex damages such as dents, fractures, etc. The plating layer is strong and not easy to come off after repair.
2. Brush Plating Repair
For localized wear and tear, low temperature brush plating technology can be used to repair precisely without disassembling the parts, and the bonding strength is better than that of thermal spraying.
The current density should be controlled to ensure uniform coverage of the plating layer.
II. Simple DIY Repair Tips
1. Surface cleaning and rust removal
Use neutral cleaner + soft cloth to remove surface dirt; stubborn rust spots can be dissolved with toilet bowl cleaner (containing dilute hydrochloric acid) or carburetor cleaner to dissolve oxides, rinse immediately after wiping and dry. Rinse and dry immediately after wiping.
2. Scratches and minor oxidation treatment
Slight scratches can be used with toothpaste or face grinding cream (containing abrasive particles) with a wet cloth and wipe gently for 1~2 minutes, after polishing to restore the luster.
Oxidized yellowing parts of the copper paste or WD-40 antirust agent, leave it for 1 minute and then wipe it off to form a protective film against oxidation.
3. Chrome paint/spray paint repair
Partial damage can be sprayed chrome spray paint, need to first sand the rough surface and clean, sprayed in multiple layers of thin coating, to avoid hanging.
III. Repair Precautions
1. Avoid secondary damage
Prohibit the use of steel wire ball, strong acid / alkali cleaner (such as toilet bowl cleaner only short-term emergency), so as not to accelerate the corrosion of the plating layer.
Thermal spraying repair need to be careful, high temperature is easy to lead to deformation of the substrate or skinning of the plating layer.
2. Environmental and process control
Thoroughly degrease before repair to ensure the bonding between the plating and the substrate; apply protective wax or petroleum jelly to isolate moisture after polishing.
Vacuum plating should be operated in a dust-free environment to prevent impurities from mixing with the plated layer.
IV. Daily Maintenance Suggestion
Regularly clean the surface with neutral cleaner + soft cloth to avoid dirt accumulation; avoid high-pressure water gun directly on the edge of chrome plating when washing the car.
Apply chrome-plated special protective agent or car wax every quarter to delay oxidation and fading.
Through a combination of professional restoration and easy maintenance, the appearance of chrome-plated parts can be efficiently restored and their service life can be prolonged.
