Hi All
Just wondering if anyone can help.
I have rust on only two spots on my car but it is the same on both sides. It is just forward of where the suspension swingarm type thing bolts on just past the forward edge of the rear wheel web. It is mainly in the area of what looks like a small square lifting point about 4 cm in size. I was wondering if anyone else has had corrosion in this area and if so is there any way I can get to it from above and if anyone has had it repaired, what did it cost? My cills though are new.
Cheers
