Overspray management

[JimmyL]

Well, my wagon was being worked on by my son who is a high school senior. He had auto bodyshop class in the mornings (just graduated!), and was fixing dents on both wheel wells on drivers side. I had also replaced the drivers door with one that had several coats of old cracked paint, so basically the whole left side was repainted and clear coated.
Well, this was his first and only paint and repair job, and I didn't have real high expectations. Well, it is basically a disaster!
There are clear coat runs everywhere, the white paint (real MB paint) isn't even close to the right color. Well, that's all great. Just great... But to complicate matters, there is overspray on front bumper, grill, hood, windshield, top, rear glass, A-pillar black portion near fender for 3", etc.....
So, I'm stuck with the paint difference until some year in the future when I can pay to have the damage reversed plus a whole car repaint (will be cheap)
What can I do for all the overspray on:
Chrome
paint
windows
rubber

Car was dirty and dusty at time of paint, so it apprears that stuff is sealed in there also.
any ideas?????
