soft center section of steel foof cars.

[pbsdaddy]

Has anyone replaced or repaired the soft center section of the roof. In my case, a 35 Tudor sedan. I found a couple pinholes when replacing the headliner. If possible, I'd like to just paint it with some kind of sealant, but I will replace the whole thing if that's what is needed. Any ideas on some kind of sealing paint or guidance on how to replace it, (marine vinyl I assume) would be helpful.
