As you may have seen I replaced the nearside front wing recently due to a small area of rust.
Using the information previously posted up by Dave (Takestock), I removed the wing which revealed the true extent of the rust on the wing.
The metal had been completely rusted through.
With the wing removed I had access to the area behind the wheel liner and here I found a collection of grunge which was removed, it can be seen on the ground in front of the jack.
This grunge can cause rust to form and indeed there were small signs of rust where the grunge had accumulated next to the inside of the wing.
There was also a small area of rust on the front bracket that connects the wing to the chassis.
The sound insulation foam bag was removed as it had a hole in it and it was replaced before being re-fitted.
All of the exposed panels were cleaned and the wiring loom was cleaned and then blackend so the appearance went from this
The replacement wing was fitted to the car
I will be removing the offside front wing soon to check for any signs of rust and give the exposed panels etc a good clean as I have done to the nearside. It does not take long so it is a worthwhile job.
