Measures for maintaining long−term body protection
Note
• After repair work, the standard corrosion−inhibiting coating should only be restored with the
corrosion−inhibiting agents approved by the manufacturer. The following points must be observed for
body repairs.
• Always apply welding primer to both sides of the welding flange when resistance spot welding.
• Prime repair areas from outside. Prime on both sides in the accessible areas.
Seal all sheetmetal overlaps, sheetmetal edges, butt joints, weld seams etc. with body sealant.
•
• When replacing structurally bonded body parts, proceed according to the information in the respective
repair instructions.
• Only apply body sealant to primed sheetmetal parts.
• Apply top coat paint to the inside of the outer sheetmetal shell before welding. See "Paint build−up":
Paint Manual
• Build up paint on bright sheetmetal panels according to the painting methods described in the Paint
manual .
• Repair or create standard undersealing by applying long−life undersealing material.
• Preserve cavities in the repair area with cavity preservative after applying a top coat paint.
• Check that the standard water drains (plugs) function correctly or clean them after the cavity
preservation material has dried.
Prerequisite for maintaining the long−life guarantee
All body repair work must be carried out correctly and according to the specific Porsche instructions for
sheetmetal, paint and corrosion protection/preservation work. To prevent jeopardising the long−life guarantee,
a Paint Condition Report is made out 2 years after delivery of the vehicle. This condition report must be
updated annually by every Official Porsche Centre.
