Volkswagen Polo Service & Repair Manual: Fold Corrosion Servicing Notes
| Corrosion on the Fold Edges, for Instance on the Hood, Door
or also the Rear Lid |
| – |
Remove the corroded areas with
→ Chapter „Pneumatic Brush Grinder Set -VAS6446-“ or
→ Chapter „Brush Grinder Set -VAS6776-“. |
| – |
Sand the overlapping areas with P360 - P400 sandpaper. |
| – |
Clean the base surface with Silicone Remover. |
| – |
After a corrosion repair and before sealing, insulate the
base surface with Two-Part Wash Primer -LHV 043 000 A2- and then
fill with Two-Part HS Performance Filler. |
| – |
After the filler has dried, the filled area must be dry
sanded with P400- P500. While doing so, make sure to avoid
“sanding through”. Then clean the sanded areas with Silicone
Remover. |
| – |
After the filler has dried and has been sanded, the metal
edges in the fold area must be thinly sealed with a fine seam
sealant. Refer to
→ Chapter „Sealing Materials“. The fine seam sealant
must match the original state. Refer to
→ Paint; Rep. Gr.00. |
 Note
| When repairing, the seam sealant is to be returned to
replicate stock visual appearance and layer thickness. |
| Sealing seams near attachments to be installed must be
applied smoothly In order to avoid damage and malfunctions. |
| Water drain holes must remain free. |
| All threaded pins and weld nuts with M-threads, as well as
all other pins and contact surfaces for the assembly must be
functional after the sealant application. |
| The sealing material cannot be applied on blank sheet metal,
but rather on filled surfaces. |
| – |
Recreate the subsequent paint system according to the
manufacturer's specifications. |
| – |
Seal the cavities around the fold area with
→ Chapter „Suction Feed Spray Gun -VAG1538-“. Refer
to
→ Chapter „Preservation“. |
Note
| Service work is effective only when the fold area can be
sealed airtight from the inside (so that no moisture can get
in). |
