My experience with Howard's is it will make that overall cabinet look a little better, but it might not do much for the simulated roll-top sections. 

It kind of depends on how bad the cabinet bothers you.  If you like the scars of surviving all these years then lay on some Howard's and a few days later some nice paste wax.  I personally prefer the original finish with some imperfections, but everyone has their own threshold of tolerance in that area.

Also, if you refinish be careful, that strip by the knobs might be photo-finish.
