if the problem is only minor a mobile smart repairer may be able to remove the rust and repaint for a reasonable price but if the rust is serious cutting out and replacing is the only long term option. But if caught early surface problems can be delt with properly so dont put it off deal with it now. My local citroen dealer has an independent repair man working from it that deals with small repairs at a very good rate but externally you would never know he's independent so ask around at as many local bodyshops as you can till you get a favourable quote and fix the price beforehand.
i had a smalldent and scrape done on the rear wheelarch and bumper on a c3 and when he painted it it reacted and all was stripped to bare metal and repainted for no extra cost. i was glad the quote was fixed as it was a lot more work than the guy was anticipating.

I hate to be the bearer of bad news but generaly the rust on the arches is normally the tip of the problem as the corrosion starts further in and then surfaces on the arch ,have u had it undersealed or waxed and it may be an idea to have look under neath to ascertain if the problem is more wide spread,u might in the end have to fit the arch repair panels from the bongo shop but that would be worse case senario ,hopefully its just water got under the paint.hope this helps.

there's been lots of discussions on this, the problem with the rear arches is that they rust from the inside out, so best way to check how bad the problem is,is to run your hand along the inside lip (under n inside) of the arches and look for corrosion there. Undersealing wont solve the problem,as it originates from inside, you can remove the interior panels and waxoyl or used thinned underseal inside the panels, but after cutting a bongo up just a few weeks ago, i realised exactly how many different joints and spaces there are some being near impossible to get to, also there is a type of double sided tape that fixes between the 2 inner/outer wheel arch panels, and follows the shape of the wheel arch and this seems to hold the water and may be a reason that most of the corrosion is concentrated around the arches, as for a solution, I have no idea! technically speaking sealing insiode the vehicle should slow the process as your taking the oxygen requirement out of the equation.

Interesting post and confirmed my suspicions. I've let Kurust, then engine oil, run/wick down the seam from the inside (delivered by a DIY bottle and straw arrangement through the hole where the rear cubbys sit (remove the cubbys for access). You could do a more thorough job by taking hte trim panels off. it may have helped but I doubt it will confer immortality. Mine are doing well at present (just one or two suspect spots) but its only a matter of time I reckon.

I find myself wondering whether, when cut-out time comes and provided rust is confined to the immediate wheel arch, it would be possible to fit a fibreglass section (if one existed!) that looked like a broad arch trim panel (so was a deliberate feature). Doing this, you be able to access the wing interior and treat thoroughly, and because you were not then welding (which would melt and compromise the waxoyl protection) but glueing and screwing, you might achieve a reasonable solution with no more metal to rust where it otherwise tends to sit and start corrosion.

I'll fetch me cap :oops:

hi
i have similar rust issues, just small spots. I was wondering who quoted and who you were most impressed by. I'm hoping to have mine treated.
cheers
