Volkswagen Golf Service & Repair Manual: Notes on treating corroded fold areas
| Examples for corrosion in the fold area of bonnet, door or
rear lid |
| – |
Remove corrosion using
→ Chapter „Pneumatic brush grinder set -VAS 6446-“ or
→ Chapter „Brush grinder set -VAS 6776-“. |
| – |
Smooth off transitions using sandpaper (P360 to P400 grade). |
| – |
Clean substrate using silicon remover. |
| – |
After a corrosion damage has been repaired and before
sealing, isolate substrate using 2-pack wash primer -LHV 043 000
A2-, and then apply 2-pack HS Performance surfacer. |
| – |
As soon as the surfacer is completely dry, treated areas
must be dry-sanded using P400 to P500 sandpaper. When sanding,
take particular care not to “sand through”. Afterwards, clean
sanded surfaces with silicon remover. |
| – |
After sanding the dry surfacer, the metal edges in the fold
area must be sealed with fine seam sealant
→ Chapter „Sealing materials“. Ensure that the fine
seam seals are identical in appearance to the original seam
seals, as specified in the
→ »Vehicle-specific paintwork information« for the
particular vehicle. |
 Note
| |
Seam seals made during repair work must be identical in
appearance and thickness to the original seam seals. |
| |
To avoid damage or faulty operation, brush seam seals smooth
near attachments which must be attached. |
| |
Water drainage holes must remain clear. |
| |
All threaded studs and welded nuts with metric threads as
well as all other studs and contact surfaces for assembly must
be functional following the extent of the sealing work. |
| |
Sealant must never be applied to bare metal. Substrates must
always be coated with surfacer first. |
| – |
Restore paintwork structure according to the paintwork
repair manual. |
| – |
Apply cavity sealant along entire fold area using
→ Chapter „Suction feed spray-gun -V.A.G 1538-“;
→ Chapter „Anti-corrosion materials“. |
Note
| The repair can only be considered successful if the fold
area is sealed air-tight from inside (so that no ingress of
moisture is possible). |
