Hi all.

Noticed a tiny touch of bubbling under the paint along where the wing meets the panel under the headlight.

A common area for this problem

Any tips on how to delay the inevitable progress of this?

After every wash, and wax. Spray it with ACF-50 and use a soft rag or micro fibre cloth to spread it even. Best stuff available to stop corrosion progressing, in my opinion.

Hope this tip helps, thanks!

Is the paint non metallic?? if so you could take that small section back to bare metal , treat it and then repaint it. If its metallic paint then this will create a bit more work especially when it comes to matching and blending in.

Ha ha. Wash and wax? That would be every 18 months then.

Its pearlescent brg if the plate on the inner wing is correct.... Who knows though after 207 owners all adding their individual stamp to it.

Its only a small patch so taking it down to bare metal and redoing may be the best bet I guess.

One more item on the list that I don't have tome to do. Lol

Treating the rust from the shiny side only is futile. Your looking at the end result. The rust will have started from the other side, so you need to get to the inside of the wing, treat the rust properly with a stabilizer, apply a zinc primer and protect in suitable underseal. Then you can deal with the shiny side in a similar way but with your primer and top coat. If you just do the outside the rust will return very very quickly.

Well that was my question really. I couldn't see why that part would rust from the outside. The water doesn't collect there and sit.

It can't see that its rotting through from the inside though. Its too solid if you dig there.

I don't know what the arrangementis on the inside to know why that place in particular would be prone to rust. You see it on lots of minis.

Sorry, didn't realise you wanted to completely remove the rust. you asked originally the best stuff to stop it progressing, and I thought something like acf-50 would do the job.

The panel joints have flat seams on the inside which are spot welded together in the factory. Over time water will find its way between the seam joints and corrode through. If you get to the inside and go at it with a screw driver and wire brush you'll probably find "issues"

Can you feel / see up there from inside the wheel arch? I can't remember off the top of my head.

Can with car jacked up safely and roadwheel removed 

[jime17]

Cheers. A bit worried about what I'll find but you never know.

The biggest problem that once its in the welded flanges its a big job to sort it out. You can cut sections out and replace them BUT and its a big BUT there will be more than what pops up.

 

With what you have got all you can do is to do damage limitation. When it gets too bad then its panel changing time or at the very least sections of the flanges.

Oh Goody.

so worst case could mean replacement of wing and bottom rail between wings (don't know what its called) could need replacing?

That would be worst case, the best thing to do as already said is to get behind the front panel and wing and have a look to see what's going on.

 

You can go on for quite some time just carrying out localised repairs but as and when it gets really bad then its time to change the whole lot. That way you can ensure there is something between the flanges and seal them up.
