The arches on my CLK are showing signs of rust. I had this treated very successfully by Benzworx on my previous one (now written off) but they appear to have stopped trading. Can anyone recommend a bodyshop in the general south east area than knows what side is up and can treat the rust now, make good where required and rustproof afterwards. And I don't mean slapping on a load of underseal............ I'm in Bromley but happy to travel to wherevere will do a good job.
