Even the smallest surface aberrations can impact the aerodynamic performance of planes which fly at high speeds. At the HondaJet production facility, a pre-paint coating is first applied to the fuselage in a "crossdraft" booth where air is circulated from front to back along the aircraft body.
Contaminants such as dust and paint droplets are washed to the booth floor and removed through a drainage system to prevent impurities in the coating surface.
Next, the topcoat is applied in a "downdraft" booth, in which air is circulated from ceiling to floor to prevent paint droplets from adhering to the fuselage.
Separating the coating process into two stages has made it possible to achieve industry leading performance in both aerodynamics and aesthetics.
The HondaJet's color scheme was first adopted in 2003 for the first test model. When the aircraft was subsequently displayed at EAA AirVenture Oshkosh, the largest aviation show in the U.S., in 2005, its coloring drew wide praise from aviation fans, garnering comments such as "I've never seen such a beautiful plane!"
The mass-production model currently under development employs the same distinctive coloring, with silver, red, and yellow variations available in addition to the original blue.
