T MPAINT OPTIONS 333

The BASF Glasurit exterior paint used on all Schweizer S333TM helicopters is one of the most technically advanced paints available. It is the same as that used by premium automobile companies such as BMW and Mercedes. The nine-step paint process offers superior corrosion protection and a durable yet attractive appearance.

Four factory standard trim styles and literally hundreds of colors are available.
