Last time I backed into a lamppost and dented my car door badly. At the repair shop, I opted for paintless dent repair (PDR). The technician used hooks and rods to slowly push the dent out from the inside - it looked pretty amazing. This method works well for shallow dents with undamaged paint, preserving the factory finish. If the primer is damaged, you'll need traditional bodywork: removing interior panels to hammer out the metal, applying body filler for shaping, then three coats of custom-mixed paint before final polishing. It cost me ¥1,200 and took three days, but the result looked brand new. I'd recommend prioritizing PDR when possible, since factory paint offers better durability and higher resale value.
