Paint can be epoxies, enamel or latex base paints, cement or chemicals, tar, polyurethane foam, pesticides/fertilizer materials, etc…

Paint in the hands of a painter (one whose work is covering walls, etc. with paint) painting a high structure such as a water tower, office building, bridge, etc… and wind carries paint spray onto a parking lot where it sticks to vehicles, machinery, buildings, etc… paint finish, glass, chrome, rubber trim and molding pieces, thus creating a liability problem called a overspray damage loss.
