LD,
I have LP 104's, Nitrox sticker and whatever has to be on there - as well as my initials on top with full name below - the initials are really fat whiel full name is just written on.
You can use the sharpie they most likely use to mark your gas on the stickers or tape anyway...
I have found that the enamel type markers crack and come off somethings (fins) never tried them on a tank tho.
