The most important part of successful, good quality paintless dent repair is having a skilled technician with the right tools and experience. The more specialized the repair shop, the better the chances for having large or troublesome dents and dings repaired without the need for part painting, fillers or replacement.
The technician must first assess the damage to determine if paintless dent repair is a good fit. Because the metal is "pushed" by the tools, it is important that the damage is accessible and that the technician can reach all the edges of the dent to carefully massage the exterior to its original shape. Working from the outside in, the technician will then progressively decrease the dent until it is came in original shape.
