Ceiling panel question

[davidkerryedwards]

One my ceiling panels must have been cut a little short at the factory. There
is a section of
about 18 inches that is not captured by the plastic trim strip that goes
betweeen panels.
Various fixes had been tried by previous owners including construction adhesive
under th
panel and caulk on top of it. The ideal solution would be wider trim strip.
Does anyone
know if a wider strip is available. If not, anyone have any suggestions for
stopping it from
drooping down in that one section?
