1.0 Recommended tools.

Only use those tools designed for steel repairs.

2.0 Straightening outer skin.

"Cold" straightening: Press dents out from their center and smooth in an inwards direction with gentle taps.
In the case of small, soft dents (hail and parking damage), this is also possible without damaging the paintwork. This requires special tools and trained employees.
In the event of damage that is only accessible from one side it is possible to use a dent removal system featuring welding.
Avoid cracking.
Avoid hardening and overstretching.
Prevent overheating small areas of the outer skin.
When the surface exhibits an unevenness no greater than 2 mm after straightening, putty compound can be used to even out the area.
Unevenness greater than 2 mm with metal putty.

NOTE: Only applicable within the European Union!

European used-vehicle regulations prohibit the use of tin containing lead in vehicles introduced after 01.07.2003!
For high-security vehicle, note the special information in the repair instructions!

2.1 Straightening the wheel arch (rear quarter panel).

Vehicles in which the wheel arch is not welded but bonded and beaded can be straightened.

This is possible in the following situations:

Rear quarter panel (wheel arch) is not torn in the area of the bonding. Welding in this area is not permissible.
The outer skin has not become separated from the outer wheel arch section.

In general, the following applies:

When performing straightening work on the wheel arch, apply sealant to the inside. After straightening, the area must be primed and resealed with sealant D1. Protect from the inside using cavity sealant.
