Protect affected areas from weld spatter and dust during all welding and grinding work on the vehicle.
If metallic dust stays on the vehicle for some time, there is the likelihood of film rust formation.
Grinding produces tiny spots of damage to the paint surface, which may cause corrosion. Also use suitable protective measures to protect the interior when performing repair operations which relate to the inside of the vehicle.
For this reason, make sure to:
In addition, take into account:
Electronic components
Increased use of comfort and safety electronics in modern vehicles requires additional attention to be paid during body work.
Over voltages produced during welding can cause electronic systems to be damaged. In particular, the safety instructions for performing welding work on vehicles with airbag systems must be adhered to.
WARNING: After disconnecting the power supply and before performing further work, a wait time of up to 15 minutes must be maintained, depending on the vehicle.
Work on airbag systems may only be performed by persons who have a relevant certificate of competence.
