How to Repair a Dented Wheel Arch?
2 Answers
Prepare various lever tools along with professional lighting, repair hammers, specialized leveling pens, etc. Use the visual effect of light refraction to determine the position and extent of the dent. Apply the principle of leverage to release the tension at the dented area of the car body, allowing the surface 'entropy' value at the dent to reach its maximum, thereby restoring the dented area to its original state. Use repair hammers and leveling pens to fine-tune the raised marks on the car body, smoothing the surface to perfection. Check under lighting or sunlight; if no flaws are visible, the repair is considered successful.
Last time I backed into a fire hydrant and dented the wheel arch, but managed to fix it myself with decent results. First, pour hot water to soften the plastic (don't use this method on metal wheel arches), then push outward from the inside while it's still warm. For small dents, use a toilet plunger to suction and pull slowly; for larger dents, you'll need to buy professional dent-pulling tools. After repair, it might still feel slightly uneven to the touch, but it's hardly noticeable from a distance. If the paint is damaged or the metal is deformed, it's best to go directly to a body shop for paintless dent repair (PDR) technology. Their hot-melt adhesive puller method won't damage the factory paint and is much easier than traditional bodywork. Never use a heat gun on plastic parts—it can warp or ruin them completely.
