When I was doing roofing the pica dry mechanical pencils made things so much better. Sure a pencil works good on wood, but what about when I have to mark gray sheet metal? You need something that comes with different colors.
Those get clogged up on pre patinad copper unfortunately, and a sharpie does not work well on black prefa unless you are trying to hide a scratch. sharpie also doesn’t always wipe off well.

That’s what sharpies are for
