I have a W210 E320 cdi estate 2001 with surprising and depressing amount of front wheel arch rust. The corrosion is tracking in from edge along paint/steel interface not through the steel but has reached the outer main face of the wing. I have a feeling this model is prone to it? It would appear quite straightforward to deal with this rather than fit new wings which seems an unnecessary expense. However, ideally the wings need to come off so I can get them ‘on the bench’ but are they bolt on and if so is it an easy job or nightmare requiring specialist equipment etc? I have read all the threads etc re Mobilo/warranty terms and conditions etc and there's no chance I'd be able to claim for this. I have also read with great interest the information about models and galvanizing. This tells me the only real solution is to abandon the W210 and move on to a 'galvanized' post 2003 W211. Presumably that would mean body rust was something only found in history books?!

I look forward to your advice. PeterM

Hello and welcome to the forum. Do check behind the rubbers around the doors and at the bottom, and if necessary treat with xax oil,, you can take the front wings off,,and I could give you the info on doing that but you can get to the other side by removing the wheel arch liner

have the rusty areas treated with POR15 and then paint over the POR15. i used it on all 4 of my arches on my 210 saloon, and no sign of it coming back so far! im sure people are fed up with me banging on about this stuff, but its the best stuff ve used by a long way! brilliant. i got the starter kit from www.frost.co.uk

info is there about it too

You really need to get rid of the rust pores first ..best way of dong this is to have the wings sand blasted, grinding away the rust will only leave you with much thinner metal and lots of filling.. when sand blasted you can then treat with POR15 and stopper or fill any pit marks..

There is arguments over sand blasting . I have seen a chassis sand blasted, then on sanding some good metal has been peened over the rust and trapping it inside, I know that wings are not as thick

Sand, grit, bead, or even walnut shell are used for blasting, I,ve personally seen a set of alloy wheeels ruined by some guy using heavy sharp sand to blast them.. ..

the por15 starter kit comes with a rust etching acid, which eats into the rust and kills it, before using the cleaner to neutralise the acid, then the paint to prevent re ocurrence. i did grind down the large blisters a bit before applying the acid etc, and although it was a rushed job in poor conditions (draughty, dusty garage, failing light etc) the result was more than adequate
