Oh yes. I used to work at a commerical shipyard. Many of the owners of cars parked in nearby parking lots would constantly complain about paint overspray carried by the wind. The shipyard had a contract with a local detailer to essentially use cleaner wax to buff off the paint overspray. The stuff came right off. It can be done by hand too, but it takes a little bit longer. Claying also should work. Either way, don't let the paint bake on the finish for too long before doing somethin about it.
