Saw an interesting post over on CMMguys with a video of someone doing a study to determine the average thickness of Sharpies in various colors.
Thought it might be of some use to someone here. 👩‍🏫

Black Sharpie: .000118” /.0029972mm
Blue Sharpie: .000132” / .0033528mm
Red Sharpie: .000160” /.004064mm
Blue Dykem: .000314” / .0079756mm
Red Dykem: .000236 / .0059944mm

The poster also noted that sharpie was superior to Dykem as a chemical shim because the paint brush applicator used by Dykem was unreliable in laying down a consistent thickness.
