I have a NOS Reynolds 525 frame and fork that has just a small place that
needs to be touched up on the metal split shot that is on the bottom of the
right chainstay for the rear derailleur cable to go through..

I tried just painting it...paint won't stay on the shiny metal. I tried
sanding the paint in the area and then touching it up...paint won't stay on
the shiny metal. I have tried sanding and then priming it with a couple of
layers of different primers including etching primer...neither primer nor
paint will stay on the shiny metal.

Any ideas how to make the shiny metal hold this primer and paint?

Thanks,

Frank

Get some acetone and wipe the area that you want to paint. Then primer, then paint. It should eliminate any and all non-paint-friendly stuff in the area and give you a nice clean surface to have bond.

For understanding

As tubafreak noted, you need to solvent clean the area. It's not because the metal is shiny that the paint won't stick, it's because the surface is contaminated with oil from the cable. Chemically clean it - soap or solvent will work - and make sure it's dry. You should have no problems with paint adhesion then.
