nappy
n.— «Single one piece plastic fascias front and rear make up most of the body work including grille. Although they look substantial, there is not much behind them.…In metallic colours, recoating these large front and rear nappies as they are called in the industry is not cheap even if they sustain only minor damage.» —“Hyundai X3 Excel Hatch/Sedan (1994-2000)” by Joe Kenwright CarPoint Australia Apr., 2005.
