Newbie to the forum - lots of great information - particularly like the detailing section - wow!
One gripe I have with my A4 Avant is that the aluminium roof rails are quite tarnished/tired looking.
When I took it to my main dealer a while back they said to use polish on them to remove the 'tarnish' - tried this but it didn't have any noticable effect.
Any recommendations on a product to clean these up properly?
Thanks in advance
