Windscreen wiper hitting bonnet
I'm new to the forum so apologies if I do anything wrong.
I have recently bought a 2006 159 Lusso 2.2 JTS and when cleaning the car yesterday I noticed that I had a chip in the paint that goes right down to the metal on the edge of the bonnet on the drivers side near the windscreen. After scratching my head for a day trying to think how it was done, I found that it is actually the windscreen wiper that, when the wiper is at full extension, touches the bonnet. I notice there is a groove on the wiper arm but this obviously isn't deep enough as it still touches.
Is this a common problem and what's the best way of fixing it? Presumably if I leave it, it will just rust but there is no point getting it painted until I have fixed the fault.
Any advice would be appreciated.
