Clio 172/182 hidden rust traps

[DickP]

Hi,

I have been doing some corrosion maintenance on my Clio 182, and have discovered a few mud traps which don't appear widely discussed.

My findings were:

1. A triangular shelf area between the rear axle mounts, tucked up high;
2. Beside the fuel tank on the driver's side, adjacent the axle mounting point;
3. Behind the front wheel arch liners, bottom of the A-post;

As the cars are now getting to an age where corrosion is properly setting in without preventative maintenance, may it be worth compiling a list of areas to inspect, clean and (if required) prepare, treat and paint / protect?

Thanks,

Behind the rear 'door cards' is the classic one.

Good research for future reference, thanks for posting

Behind the fuel filler
Behind skirts and wheel arch liners
Rear inner sills behind doorcards
Door moldings and skirts trap grit which abrade the paint away and corrosion sets in.
Same for the rear arches where they meet the bumpers. Grit gets trapped between the 2 panels and wears the paint away. Then the metal panel begins to corrode.

behind the rear bumper where it mounts to the body. This wasn't mine, was a 200k car but mine looked like if I didn't treat it it would start to go in the next few years

Front inner arches from the top running towards the headlight bracket

I noticed this one too, and it's a right pain to grind out!! Also where the rear spring rubber mounts meet the body.

Hi,

Maybe someone could make this a sticky for people's future reference?

Thanks,

When people take out the rubber bungs for the seat nuts

I've seen some right states when breaking cars!

Hi,

Is that from the bungs not being replaced after removal?

THanks,

THanks,

Yes mate. Some people don't replace them and then after a couple of winters they accumulate tonnes of crap!

It shows just on the ones that never had bungs, always fucked.

Yeah and then the nuts neve come off

I've snapped and twisted the bolts off of seat rails before

This is a carbon copy of what I'm dealing with right now, those deep sections in front of the spring seats are a PITA

Look at this for rust trap that in a 172 is near to inaccessible, no problem on a 182 due to the boot floor.

Started checking the areas on mine-

Good under the bumper, but gave it a good clean and the waxoyled

One small rub mark on the exterior of wheel well (no corrosion though) - so wafted some under-seal on it .

Few rub marks on the interior of the wheel well so painted with some satin black

Next I checked behind rear cards in the inner sill.
Small amount of surface rust both side but absolutely solid

Actually looks far worse in pic than it is

Above rear beam and petrol filler need some attention but going to wait until I can get on a ramp. Might use it as an excuse to replace the beam mounts for ployflex

Where the rear inner arches meet the outer panel, if the underseals been punctured by a stone, water can creep under between the seam, visible from the inside of the car once rear side carpet in the boot is removed.

You can add the little floorpan strengthening sections with bungs in to the list. I think someone has jacked up on there before but it's taken out a big chunk of sill with it.

above happened to my 182 as some animal made a mess of jacking it up, had to have it chopped out and welded up
