Paint on boot gone matt
Discussion
If anyone able to suggest a solution much appreciated. Car is a BMW M6 in metalic black. It was immaculate however was very dirty and took it to the hand car wash today. Once they had finished and I got the car home I noticed that the boot lid (the horizontal part of the lid) had gone matt. It almost has a greyness to it. Previously it was fine. Any ideas re solution? Is a simple coat of polish the answer? thanks.
OK, it could be a few things.
1) It has some temporary coating on it, some wax stuff they didn't buff, or whatever... not an issue, just get some meths or strong-ish solvent and wipe it down, then wash with car shampoo to remove the solvent (or even washing up liquid as this has a much stronger detergent effect). See if the dull patch goes.
2) A nastier more permanent marking of the paint, who knows what? Tar remover or wheel cleaner used neat accidentally on a panel? This can be machine polished out but I'd be complaining to the wash monkeys.
3) Clearcoat failure. The worst case scenario. For some reason, they have managed to remove the clearcoat (T-cut polishing the area or something!) and you can see the duller base coat. You will need a respray and compensation.
I would take it to a local bodyshop for a proper appraisal if step one doesn't work. It is tricky diagnosing paint problems, especially when the car can't be seen close up.

Good news 
But give it 48-72 hours to see if it comes back. Sometimes you can inadvertently apply oils to paint defects and cover them up temporarily. But oils and silicones don't last too long, especially with a detergent wash, and when dry, the paint will show its true finish.
If nice and shiny, no problem and good result
May just have been unbuffed polish or wax.
