During my verification of the fascia design when I was testing the effect of the light transmission I noticed something.
Although the guys in the machining shop had done a great job on the channels and the chamfers on the product, these surfaces were especially important for viewing the object at different angles.
Thankfully, due to my motorycling days I was farmiliar with the process of polishing aluminium to a mirror finish. The process involves rubbing down the surfaces with increasing grit wet & dry, then following with a rubbing compound, and finally with autosol to give it a perfect shine.
I also polished the outer chamfer and rim of the object because I felt it gave a better transition from the high gloss to the surfaced finish of the aluminium.
