Also within this zone, sound pads are added to the floor and boot to reduce road noise (standard practice in the motor industry). The next booth it enters is the 'Underbody' Booth. In this booth, similar to 'Sealing' Booth, the body's wheel arches are sealed using the same PVC based sealant. Robots then apply the underseal to the underfloor and wheel arches. Also robots are used to apply the SGC (Stone Guard Coat) layer to the sills: this coating is designed for abrasion resistance, i.e. preventing stone chips, scuffs, etc. From here, the body proceeds into the Undercoat Oven. The next zone is 'ED Sanding' booth where the body is inspected for any minor imperfections received in the ED Coat. The next zone is the 'Surfacer' Booth, where the body receives its second coat of paint, this being the Surfacer Coat, then into the Surfacer Oven. Next is 'Surfacer Sanding' Booth: the same as ED Sanding, this zone inspects the body for any imperfections picked up within the Surfacer coating. Next comes the 'Topcoat' Booth, where the body receives its final coats of paint, these being Topcoat and Clearcoat layers. After being stoved in the Topcoat oven, the body then enters the 'Touch-up' Booth where the body has its final inspection for any imperfections picked up in the Topcoat process. Once the body leaves here, it then moves on to the PBS (Painted Body Store) above Trim and Chassis to await the next step in the production process. Over £10m has been invested into the Paint Shop, in readiness for the upcoming introduction of Infiniti models Q30 & QX30, making Nissan Sunderland, the first plant outside Japan to produce this luxury brand, alongside its current models. Plastics shop Plastic components such as bumpers are injection-moulded on site. Plastic Paint Shop Bumpers molded in the Plastics shop are painted in the Plastic Paint shop which directly feeds Trim & chassis. The shop uses a combination of manual sprayers and robots to coat up to 900 bumper sets per shift. The process in Plastic Paint is similar to body paint, the parts are washed in a Powerwash facility before being masked (dependent on trim level). From here the parts are painted with primer, then basecoat, some colours get two coats of basecoat at different stations (Pearlescent effect). Then all part receive a layer of clearcoat before being stoved in an oven. Casting
