Check

1

Wash vehicle thoroughly and park it on a ditch

The use of improper products for vehicle washing can damage painting and cause premature corrosion.

2

Check cabin painting in general

Locations more vulnerable to corrosion would be regions under sealing joint rubbers.

If there is cabin corrosion, repair it and do a separate billing.

3

Check plates joints and doors pillars for rust spots

4

Check under windows glass rubber filler (arrows), windshield, cabin rear panel, ventilator window and doors for rust spots

5

Check if corrosion exists around all components attachment points

6

Check open cavities existing in lower part where residue and humidity accumulation contribute to corrosion build up.
