Looking nice! In regards to the chrome rings in dashboard, just a couple days ago while working on my car, I overtorqued the water pump bolts on the aluminum water pump housing. I ended up pulling a bunch of M6x1.0 threads out the holes. After the moment of anger I realized those broken threads look really fine and round. I wonder if "chrome rings" could be made using simiar method of making threads through aluminum plates out of taps, then intentionally pulling the threads apart by shearing them off with a bolt.
Just got me thinking, that's all.
