Curing it under heat and pressure in an autoclave consolidates the laminate and drives out trapped air that would otherwise show as flaws in the finished surface. Other processes introduce the resin at the mold, so the ratio is set during layup rather than before it.\u003c\/p\u003e\n\u003cp\u003eA grille frame is the single most-photographed part on this car and sits at eye level on approach.
