I also work more with Aluminum then steel. For aluminum I use 2 options. Either the "
Peter Tommasini way" I call it... where you take a scribe and scratch through the paper to leave a mark or I use my spring punch which allows me to use very light tension and leave a light mark. You can see my use of this Spring punch in my chapter in the new book "Power Hammers" By Bill Longyard.
I have found that even with using a heavy center punch mark on aluminum to transfer lines to the oposite side of a panel it is not a problem. Once you run it through the wheel or hammer a few times the marks are almost gone.
Now I know nothing about Air Craft manufacturing but I do understand they are so strict on marking aluminum that you can not even use a Graphite Pencil or scribes to mark.
