This may sound weird but a bit of masking would prevent the problem in the first place. Spraying without protecting the surrounding surfaces is not a good idea. The overspray has to go somewhere. It usually finds it's way to unprotected areas on our airframes.

Aerosol cans are much worse than spray equipment, too.

I recently painted three airframes within a month. Two were using HVLP spray equipment. One was an aerosol. The aerosol supplied 5 times the overspray, as the other two paint jobs, combined.
