Overspray and it doesn't sound like he knows what he's doing. I would wash and dry the car first and then clay bar it. Then you're going to need to compound and polish it to bring the smooth and glossiness back. You're not gonna be able to do this by hand you'll need a machine. Porter cable 7424xp is a great machine to use. If you don't want to do this yourself take it back to the body shop and demand a refund.
