When an airplane is taken out of service for maintenance, it is often repainted as well, and during the repainting no other maintenance work can be done on the plane  In order to reduce maintenance time, airline officials are considering using a new nontoxic plastic film instead of paint
The film takes just as long to apply as paint does, but many other maintenance tasks can be carried out at the same time
Unlike paint, the film gives a milky tone to certain colors.
