ACT can mitigate your losses both monetarily and administratively:

Industrial Paint Overspray
Oil Deposits
 Tar or roofing overspray
 Ferrous Oxide (rail dust)
 Industrial fallout / Chemical emissions
 Polyurethane Spray Foam
 Acid rain
 Asphalt (paving materials)
 Road Spray (from freshly painted road striping jobs)

Some things a claims handler can do to be proactive with an insured are:

Recommend weather research be done prior to spraying.
Notify and/or move potential vehicles out of the direction in which overspray can drift and produce overspray claims.
Provide Car Covers for potential overspray claimants.
Use Windsocks and other Weather Devices to determine wind direction.
