I recently purchase a used Colnago frame constructed back in middle

problem.

Any advice you may have would be greatly appreciated.

Buy a piece of thin teflontube maybe 5" long, place the tube at the
cableguide and fixed it with a drop superglue, run the cable through
the tube and the cable work perfect without touching the paint.

I don't think you really need the super glue. I had a similar issue
with my Colnago and the teflon tube didn't need to be glued or
otherwise attached to the frame and it worked fine.
