What is the method for repairing a dented car rocker panel?
2 Answers
To repair a dented car rocker panel, it is necessary to go to a 4S shop for welding new corner materials. Below is the relevant introduction: 1. Materials for car rocker panels: The materials used for car rocker panels are generally metal or aluminum alloy. Aluminum alloy is relatively easier to repair due to its certain degree of elasticity. Repairing dents in metal or aluminum alloy rocker panels is more complex compared to plastic materials, as metal surfaces are usually coated with a layer of particles. 2. Car and rocker panel integration: Whether the car and rocker panel are integrated also affects the difficulty of repair. For models with integrated rocker panels, repairing large-area dents can be more challenging, whereas detachable rocker panels are relatively easier to repair.
I've repaired door sill dents several times, and experience tells me the approach depends on the situation. For minor dents, you can try using a toilet plunger or specialized suction cup tool to pull them out. When operating, first soften the rubber seal with a heat gun before applying gradual force, avoiding excessive pulling at once. If the metal is severely deformed or has curled edges, it's best to have a professional perform metalworking: first sand off the rustproof layer, use a dolly to hammer out the dent, then use a dent puller for spot welding repairs. Remember to reapply rustproof treatment and repaint after repair, otherwise rust may develop. It's advisable not to DIY plastic sill repairs - improper use of a hot glue gun for pulling may cause plastic cracking.
