Difficult to say from the photos but this looks very close to a similar type of contamination that used to be common locally. The overnight output from the local oil refinery regularly left shiny irregular spots all over the paintwork. The only way to remove it was to polish it out, but it does polish out with relatively little effort. It’s worth a try and if it is, then it’s probably local air pollution or something that occurred during shipping.This is an example, there are 2 here, 1 being pointed at and 1 directly south-east of it. They are quite hard to photograph and I didn't notice them at first and thought they were limited to the bonnet, which had about 7 or 8 of them, however on closer inspection at home it looks like there are the odd one or two on probably every panel.View attachment 844625
