Hello,
Just joined site and got a 2000 CLK coupe. Spotted this very relevant information for my situation.
I've got a few rust spots to be treated around wheel arches and on driver's side rear arch, hiding under AMG side skirt.
I'm paying £1300 for 2x front wings and 2x quarter panels, which think is pretty good from a well recommended independent paint specialist (perfect paint, Sandhurst, Berkshire)
They advised they have to repaint all panel to blend the paint and lacquer colours into the overall, and to minimise the chance of rust coming back too soon.
I can't do anything mechanical myself, and think for this MB ailment getting it done properly and best possible will be better in long run as rest of car is solid.
Best Regards,
Stuart
£450 is paint, £850 labour
