Our Repair Techniques
WHS has specialized in the techniques of PDR – Paintless Dent Removal, or REPAIR WITHOUT PAINTING.
This system has been the ideal solution for many years and has been chosen by the automotive industry for the restoration of cars with dents that do not require any filler or coating (eg. Hail damage, door dents, creases, small dents, etc …)
The use of these advanced techniques and the very latest equipment allows us to act on the damage, operating directly on the sheet metal (aluminium or steel):
- with methods of pressure and “massage” (using levers) for parts where the technician can reach the point from inside the vehicle, through openings and windows or removing interior panels;
- with methods of traction adhesive from the outside (using heat glue) when the technician can’t reach these parts from the inside. For example, if the damage is over a point where it passes a reinforcement. All these techniques are used to transform the sheet metal of the vehicle as if it had never suffered any damage.
This method bases its concept on the elastic properties of the metal; due to its flexibility it is possible to carry out work using techniques available to our professional technicians.
Using these techniques the delivery time is drastically reduced and we can deliver your repaired vehicle in 1-2 days compared to 7-14 days necessary using the traditional methods of body shops, (depending how bad the damage is).
PDR works best on plates that have superficial dents, which are not too deep. For deeper dents one of our Managers will assess if it is possible to repair using PDR.
The “Fluorescent Lighting Procedure”, or in some cases a reflective panel, can be used to see the shadows created by the deformation of the dent.
PDR would not be the recommended procedure if:
- the metal was bent or cracked;
- the paint was severely impaired or frail, but PDR could still be used to reduce the body shop costs, then proceed to the paintwork (“push to paint”, or “push for paint”);
- the damaged portion had undergone previous repairs using traditional methods of bodywork, such as the presence of filler (to be considered case by case).
