Wow, that guy was just stupid. Sorry. I get wanting to touch up the paint, but really... It looked decent enough. And maybe it's the lighting, but did he change the colour? Looks more like an orange hue before, and now it is clearly red.
Sorry dude, that sucks. I would personally start with cleaning up the spinner, but there isn't anything, realistically, that you can do with the rest of the plane. Brutal. But think how fantastic it will be to have a beauty new paint job that you can design!
