Paint to mark a blank w/o adding much thickness?

[fishwizzard]

Hi,

 

I have a telescoping rod, a Daiwa BBB, that I bought years ago to use when hiking with non-fisherman.  I wanted a combo that I could stow and ready for action quickly as not to waste too much of my friends' time when we pass a spot that is too good looking not to fish.  Sadly the plan didn't work.  The rod is wonderful, but between the 6 sections and the floating guides, it takes a long time to get it set them all up in-line.  For some insane reason alignment dots were not added at the factory and I would like to add my own, but am wary about adding any thickness to the blank.  Can anyone suggest a paint that would work? The blank is semi-sanded with a gloss finish, I can provide pics if that would help.

Paint goes on in thousandth of an inch, unless you get crazy your dot should be in the neighbor of the thickness of a sheet of paper.

A dot of red nail polish? Or model airplane paint? Would a sharpie work...this is probably what I would do...  I dont think it would hamper the weight or action.

I use a paint pen, the same one I write on blanks with, it's white, but I also have gold and black.

I have had my day ruined by the thickness of a single coat of paint before, so I wanted to ask. A silver sharpie will not stick to the blank, I will try to hunt up a paint marker.
