I did this to make the bolts look good, keep the original ones, and protect them from rusting in the future.
I also put a "bluing" finish on some of the bolts that I had wire wheeled because they were too shiny and not original looking. They turned out well.
I have a friend to see tonight, Caroline is coming tomorrow, and Mom on Sunday so progress will probably be slow. But, fun nonetheless. I am going to put on the front beam and do brakelines next.
