There is black tape on the center pillar between the doors on my 93 RMS, and it's bubbling and coming off so I started peeling it off completely.

What's the best way to make them black again? Paint them or tape them. Anyone else had this problem?

Most likely they are painted. Another option...Electrical Tape. I used ET to cover the Chrome Bumper inserts on my Black Caprice bumpers.

It covered them and held up well for years and looked pretty good until I could replace them with Impala strips. It wasn't quite as shiney as the painted bumpers but matched pretty well and looked better than the chrome. It even had a seam cause I needed 2 pieces of 1" wide ET I had. You may be able to find some wide enough to cover the pillars. If you don't like it, just peel it off.
