pannel lining

Im currently working on an Ultimate Unicron and i wana do some Pannel lining. However ive never actually done pannel lining before
i want to make THIN lines and ive heard the best way to do this is with GUNDAMN MARKERS. But ive seen afew pictures and the markers seem rather...thick... basically.
Is a very thin Gundamn marker the right way to pannel line? will the actual ink STAY on the figure when i try to transform it? it wont just rub off or anything will it
