Having same problems, with multiple pics, so..
A quick visit with Helga to the local car paint shop , and a few rattle cans of colour matched paint along with plastic primer and clear-coat where purchased.
In my paint shop (well shed at work with lots of dust sheets) I prepared and sprayed it over 3 days. Very happy with the result, it is a little more shiny than Helga, but she is a little dirty and hopefully the box will weather a bit. New locks fitted (with the same key!) and all looks good. Will probably move the camera for a better view when reversing.
