Shafers model car thread

This is def a cool thread!!! I have a bunch I've built. Some of the pics I saw in here are beyond my patience point. How do you guys get the silver/chrome window trim so perfect? I have tried that a few times since I was a kid and it always looks sloppy and wind up just painting over it. I've tried ink pens, paint brushes, and even dipping a needle in silver testor paint.
