Can't quite remember what this was about now - the only thing that springs to mind is just how to use brasso properly. It needs to penetrate the surface of the metal, so you have to work it in as if you're kneading bread almost. Really does take some elbow grease, it's not like polishing bar brass.
I'm curious about
Care to share the process? This looks as good as those ball burnished alloy GTs from the 90s. Great job.
