Any ideas as to what is going on here?     Only noticed the other day, but these pictures are taken on my wife's July 2021 registered C-HR ... The orange stuff looks very much like rusty iron particles. I've cleaned up the lower part of the left hand side drainage channel and while it's a bit stubborn and well 'stuck' it doesn't appear to have damaged the paint underneath - well, not yet at least. There's quite a lot on and around the hinge fixing points and settled in the rubber seal along the top of the tail gate opening but I can't quite make up my mind as to the source or cause. Since the car is less than a year old, the wife will probably simply take it back to the dealer but any suggestions as to what I might best to to sort this? |

Might be a daft question but are you sure it’s rust? Could it be a build-up of that red sand blown up from the Sahara recently?🤔 |

Apart from the 'rust' it looks like the tailgate has been adjusted looking at the hinge plates. Any idea why?

My beloved opened the tailgate while the car was in the garage - and then reversed out! The car with an open tailgate didn't fit through the doorway. So that cracked some plastic trim, and a very expensive rear light cluster. We don't talk about it ...  But it also adjusted the fit of the tailgate and the garage had to adjust it back again. I deliberately 'forgot' to mention that detail in my earlier post so as to get a view based on the evidence alone. It would be all to easy to 'blame' the garage - but I can't see what they could actually have got wrong to cause this problem. |

Just wonder if, for any reason, there had been any drilling or filing involved when the repairs were done?

Looking at the photos, the one that I find odd is the rubber grommet going from tailgate to body, it has rust marks on the top of it ?
I’ve seen this In my motor trade days and was down to a grinder being used, then the hot metal filling landing on the paintwork and then goes rusty.
So has it had bodywork done or been in a workshop next to a car having grinding sparks flying everywhere 😠😠

I’m kinda with Jim in it looks like something on the surface rather than rust coming up through the paint.
Do you have any ultra low cut wet and dry that you could very carefully try to remove it ? I would lube it with WD 40 and go really easy.
You could of course head straight to the dealer but they will charge you if it’s contamination of some sort. Dirt dust and crap can gather in that area.
EDIT. You have that contamination on the plastic cable trunking, My bet is contamination and I’m hoping whatever it is isn’t causing corrosion.
Has someone gone a bit mad with with the lube for the hinges ?

Just one piece of plastic panel on the tail gate, a light cluster and the badges to be replaced ... It looks like rust / swarf and could be associated with the repair ... but it could just as well be 'red dust' that has washed down from the sky while the car was being driven along ... |

Has someone gone a bit mad with with the lube for the hinges ? Agreed - it is certainly some form on contaminant on the surface rather than rust coming up through the paint. I've successfully clean some of it off from an easily accessible area with nothing more than car shampoo. As you suggest, I'll do my best to clean the rest - if I am successful then job done; if it has to go back to the dealer I still have the photos ... |

Unless the contaminant was somehow applied or occurred at the dealers it’s not their problem. They may clean any that you can’t remove but will charge for doing it. If you struggle to remove it then the lightest of wet sanding using 4000 grit wet and dry used wet with WD40 should remove it easily. |

Photograph it first, so that you have later on proof that it happened before should it recur after cleaning. Edit…..cannot believe I typed that in good faith……Inam LOOKING AT PHOATEEZ OF IT.

So, I started to clean it off, initially using an old paint brush to brush it away. And I wondered, if it were swarf or rust, it might be magnetic - and sure enough it is:  And then I asked Google whether Sahara dust is magnetic too - and sure enough it is ...  So, back to square one and carry on with the cleaning! |

That's better:    Jim was quite right - it was indeed a build-up of that red sand blown up from the Sahara, and there's no sign of any damage otherwise. :TU: Simply brushing didn't do much, so I had a go with snow foam from a hand sprayer - which shifted much of the discoloration and a surprising amount of the grit but didn't really touch the well stuck bits and the "encrustation" around the door hinges. It turns out that the cure for red rain from the Sahara is Purple Rain (from Autobrite Direct (rather than Prince)) and a bit of agitation with an old toothbrush. And then much rinsing, a wash down with car shampoo and another good rinse ...  |

So here we have an answer for the amount of people who ask, condescendfully, “Why do youz anal folk bother with all that foamy-woamy pre. wash shit….?”
Can you imagine Philip washing his car withoot a richt guid rinse, and rubbing in his lovely red magneticky bits…? Result…..pink Etch a Sketch car ffs…? Good article this.
