The main principle behind the working of paintless Dent Removal is to apply pressure gently on the opposite side of the dent or ding by using specified tools, so that the metal is pushed back to its original shape without disturbing the car paint finish. The technician tries to align the localized dented part by using lightweight hammers. Any irregularity in the damaged part is then corrected by light taps or gentle hand manipulation. The effectiveness of PDR depends on the paint quality and the severity of the metal stretch that has been incurred by the damage. While performing PDR, the technician applies the pressure with proper eye and hand coordination.
