Volkswagen Golf Mk7 Service & Repair Manual: Corrosion protection measures for wing surface in contact with wheel housing liner

Note: new replacement Volkswagen Golf Mk7 wings without factory sealant need corrosion protection applied to the groove area — this page explains why, to prevent the wheel housing liner from trapping moisture against bare metal.

  Note
  The corrosion protection measure is to be carried out in the groove of the wing of all new replacement parts which have not had the additional sealant applied at the factory.
  The additional sealant is intended to prevent the wheel housing liner from possibly “scouring” the groove of the wing, which could cause corrosion.
–  Apply surfacer on inside and outside of wing.
–  After surfacer has been applied and has dried, apply and spread sealant -D 511 500 A2- in the contact area of wheel housing liner (groove of wing).
