Body Repairs - Paintless Dent Removal - Paintless Dent Removal Maverick 2005 (08/2004-)
Description and Operation

General

Small minor dents can be repaired without damage to paintwork. The dent is worked from the inside using special levering tools (pressure tools). The pre-conditions are that the diagnosis is certain, the correct repair method is identified and that the technician has enough experience in the use of the special tools and knowledge of the working materials.

  • This option is limited to those bodywork surfaces which are accessible from both sides. This repair technique is seldom possible on double skinned bodywork components or closed bodywork profiles. The same applies to edge areas, beads and folds in bodywork components which are very rigid.
  • Satisfactory results are only possible for minor dents that are shallow and with a small deformation radius. This method is therefore particularly suitable for damage arising from hail, parking and transport.

Economic considerations

  • Whether it is economically worthwhile to carry out paintless dent removal depends on:
    -
    The area and depth of the dent.
    -
    Access to the repair area.
    -
    Rigidity of the repair area.
    -
    Suitability of the material
    -
    The number of dents over a particular body panel area.
    -
    Whether there is already any paint damage present

Extent of the damage

The repair method is suitable for dents up to approx. 50 mm diameter.

Pre-requirement for the repair

The material at the centre of the dent must not have stretched.

Repair procedure

  • Diagnose the damaged area.
  • Mark the dent.
  • Prepare the area to be repaired.
  • Put the adjustable lamp in position.
  • Reshape the dent.
  • Renew the corrosion protection.
  • Carry out quality control.

Repair tools/aids

  • Special dent removal levering tools
  • Adjustable lamp

Repair Procedure

  1. Decide on the repair method.
  1. Mark the dent
      NOTE:
      NOTE:Do not use a pen containing solvent (paint damage).
    • The dent is marked in the repair area to help recognition.
  1. Prepare the repair area
    • It must be certain that the inside of the dent is accessible. Repair openings must not be made.
    • Clean the bodywork in the damaged area. Good visual checking is vital to success.
    • Polish the repair surface if it is matt. The repair procedure can only be checked exactly if there is enough reflection of light.
  1. Place the adjustable lamp in position.
    • The adjustable lamp should be positioned and adjusted so that the dent can be clearly seen in the reflection on the paintwork (oval shape).
    • When pressure on the dent is increased the oval shape changes into lines which cross over each other. The point where the lines cross is the pressure point for the pressure tool.

Pressure applied to the dent
  1. Position the pressure tool
    • Position the tip of the pressure tool on the edge of the dent.
    • By moving back and forth with light pressure applied on the dent with the tip of the tool, the reflected light shows the position of the pressure tool.
  1. Working principle while applying pressure
    • The operation concentrates on forming a half circle, working chronologically.
    • To restore the surface, all that is needed is to work on one half of the dent.
    • The unworked half of the dent restores on its own, through tension produced by the pressure.

NOTE:
NOTE:Never begin in the centre of the dent. If a dent is worked from the centre first, the edge will be lifted up and will remain visible as a high area (material stretching). This lifted edge can only then be restored by lengthy reworking.

  • Exception:
    -
    Sharp edged dents with minimal material stretching are first worked on at the centre.
    -
    After pressing out the dent, slightly raised areas can be seen. This is caused by the excess steel in the centre of the dent, caused by material stretching.
    -
    Use a plastic drift to even out the slightly raised area.

Unstable pressure area

If large, relatively weak body areas are worked on, the path of the pressure tool while pressure is applied is correspondingly larger. The restoration process takes longer.

Stable pressure area

  • NOTE:
    NOTE:Work areas near internal reinforcing with only light pressure, so that high areas are not formed (material stretching).
    Stable pressure bodywork areas with inner braces have a much more stable surface than weak pressure areas. Only short pressure movements are required here because the steel of the bodywork is less sprung.
  • Particular care must be taken with the pressure procedure if tools with a small contact face are used.
  • Optical check:
    -
    It is only possible completely to remove all remaining unevenness by making continual visual checks of the surface using the adjustable lamp. In addition, towards the end of the pressure procedure, the dent must be checked several times from different directions. To do this, change position by about 90°.

  • In order to make it possible to exert force in the roof area, a pivot in the form of an S-hook must be used.
  • Only loosen the headlining locally, depending on the number of dents and their location.
  • Dents near interior components can be reached by removing the component (interior lamp).
  • Check accessibility before starting repair work if the dent is near the sliding roof.
  • Repairs near inner braces are worked using the special tools found in the tool kit.
    -
    Separate the adhesive bead of the brace using a metal spatula, so that the pressure tool can be put in position.

Door area

  • Dents in the upper half of the door can usually be worked on without removing the inner trim.
  • When the window is open, access is obtained through the window cavity. A protective assembly is inserted into the window cavity to prevent damage to the window.
  • The plastic wedge ensures access.

  • The pressure is applied in this case without use of an additional support by simply turning the bent pressure tool.

Hood

  • The hood is moved into working position using telescopic struts and held in position using the "rubber cords".
  • In the region of the braces the adhesive bead must be partially opened using a metal spatula to give access to the dent.

Renewal of the corrosion protection.

  • All repair inner areas must be reworked, where accessible the paintwork must be refinished.
    -
    Clean the inner area with silicone remover.
    -
    Prime and paint the inner repair area.
    -
    Finally, spray in cavity protection where the repair is not accessible.

Quality control

  • In order to achieve a repair quality that meets production standards, the following points must be observed:
    -
    Check the repair area for unevenness. Do this optically by looking at the surface from different angles.
    -
    Paint the repaired surface area, clean it and polish it if necessary.
    -
    Check that the attached components and inner trim are seated correctly and are not damaged.
