What would be the best way to address this? I'm thinking get it blasted with a small sand or media blaster, then some rust converter/primer. From the looks of it there is supposed to be some weather stripping or something over it. Is that the case?

Surprisingly the t-tops do not leak but I want to stop the rust before it gets any worse.

Blast it. Anything rotted through cut out and replace.

 

Have you removed your center bar to see what's hiding under it?

 

No, not yet.

I would recommend removing the t-top bar for sure, my rails looked like yours, and my car had some pretty serious rust under the t-top bar (which came off in about 10 sections).

 

Yeah , your not going to like this but with that much rust showing your going to have to pull all that rubber out of there because I bet that underneath all that nice rubber there is a rust field. Im restoring an 87 and mine was not showing as bad as yours but as soon as I took all the rubber out and the center bar whoa !!!! surprize surprize. But all of my car is going to the metal so was not a big issue.
