that doesnt look like corrosion it looks like the paint didnt stick, spray it with some fluid film /
Wait instead of that get some sound deaden material clean the surface,
and put this material onto these areas for a quieter ride

 

thats what i will planning to do... there was no sound proofing at all on doors and on all car, dismanteled all completelly. which shouldnt be the case of 200k car.

and on the picture is corrosion, confirmed by 3rd party. Will fix it, but shouldnt be JLR responsible or warranty for those issues?

 

The videos don't work on my iPad, but: I thought that the doors should be 100% aluminium, or are there some structural steel bonded to the alu inside the doors causing galvanic corrosion? Is that what you are saying?

 

i cant attach video somehow... .but im adding more pictures. how its done, is that "sound proofing" is added sticker in a middle of the door, then it was painted around it, so sticker was done on top of the alluminium, then corners of the sticker (sound proof) letting water in , because its not properly done. then water goes in through plenty of holes in doors, as whole car is close to none of soundrpoofing, and water stays in that sticker and corossion starts. this is a car which is 2 months old, and driven in Mata (warm weather, little of rain). I can imagine how cars in UK look alike when you dismantle that, car realistically should be thrown away in 2 years. its a dissaster job on them done. And all car like this, im taking pictures one by one, will be contacting manufacurer to explain me their "quality" work.

 

That does not look good. I would take it back to the dealer and have them fix this under warranty before you attempt adding any sound insulation.
