2 Answers
Repairing wheel rims can be done through the following methods: 1. For damaged wheel rims, welding technology can be used for restoration and refurbishment; 3. For gaps on the rim edges, perfect repair can be achieved through build-up welding, leak testing, and surface treatment; 4. For twisted or deformed wheel rims caused by collisions or impacts, specialized wheel rim repair equipment and techniques can be used to reshape and correct the damage. Wheel rim maintenance methods include: 1. Regular cleaning; 2. Using the correct cleaning agents; 3. Avoiding washing when the wheels are hot; 4. Cleaning aluminum wheel rims. Wheel rims should be stored in dry and humidity-controlled environments, placed on racks rather than directly on the ground, and contact with related chemicals should be minimized.
I've repaired scratches on my alloy wheels before, and the process is quite meticulous. First, thoroughly clean the wheel stains to reveal the bare metal. For superficial scratches, gently sand with 600-grit sandpaper until smooth, then apply professional body filler to fill the pits. After it dries completely, use 2000-grit sandpaper for fine polishing. The painting stage is crucial - apply three thin coats of primer and topcoat with 15-minute drying intervals between each, finishing with a clear lacquer protective layer. Remember to wear a respirator and work in a well-ventilated area. Severely deformed wheels must be professionally straightened using hydraulic equipment - amateur hammering can cause metal fatigue fractures. Post-repair, wheel balancing is essential - apply counterweights on the inner rim to adjust the center of gravity, otherwise vibration will occur at high speeds.
