Hatch Mid-Wing in gloss black thermoformed ABS without coating, with 3M acrylic plus attachment tape. For this durable ABS part to receive a fit and finish above typical fiberglass aero parts, we 3D laser scanned the car, CAD design the part with perfect symmetry, 3 axis CNC machined the mold, and we 5 Axis edge trim each part. The sharp machined edges need sanded smoth for the best feel and appearance. After removing all emblems and test fitting, like all ABS plastic parts, you will block and hand sand with 600 and 800 grit. Finishing: Apply adhesion promoter. Epoxy primer, wet sand, wax and grease remover, basecoat & clearcoat. Install: apply 3M tape 1-2mm inset around the perimeter allowing some gaps at the bottom for moisture to exit. Partially peel back each double stick tape line's red cover leaving a tail to pull past the perimeter. Lightly adhere & confirm the part is level and mounted with symmetry. Pull the rest of the tape liner and press firmly ensuring a permanent bond.
