[mass A man]

When I had to use a point file, the points were pretty much history anyway. It will get you going again but soon let you down since the ignition points were protected by a very thin coating of platinum. once you file that off, you're down to the unprotected base metal. If you need to clean the points, a VERY fine stone, or a very fine "flex-stone " burnisher strip. The point faces need mate up perfectly when closed for great results.
