Either SW ProClassic or BM Impervo should work for you. Both are used often for kitchen cabinets and woodwork. I used SW ProClassic semi-gloss in white to paint a half wall of 60's paneling and a built in bookshelf and it looks great and has worn well for a couple of years. I've noticed no peeling, chipping, scratching, or chalking.

Cabinet Coat which is found at Ace Hardware, I believe, is also recommended often is this forum.

Is your existing Satin Oil paint on the shelves a PRE-tinted Black from the factory...

OR,

Is it a store-tinted color with a formula-label?

Search out a PRE-TINTED Black in Semi-gloss or Gloss.
ACE has-'em too. Call around first...
In High-Gloss, I've even got ACE Latex half-pints of Black, in addition to Qts.

Rule out Eggshell NOW.
It's just not a tight enough resin for this use.

Cabinet-Coat will only tint to Pastel tones.
(I WISH they had a pre-tint Black tho!!!)

Cure-time b4 ANYTHING goes back on?!?!
A month or more....
Not what you may WANT to hear...but it's what you HAVE to hear...:-(

You COULD look into an FPE Black. That stuff is UNreal.
