This is a 30 x30 garage with a metal roof. I think it is a 3 or 4 12
pitch. My ideas was to add 2x4's every 4 feet between trusses and use
7/16 osb for a ceiling. If everyone here thinks it might sag or is a
bad idea, I thought abotu using 4x8 insulated panels? I wonder how
that would look?

Read (and heed) Bob's (aka fft) answer -- it depends _entirely_ on the
truss design and we can't tell from here.

Chances are you're ok, but you need to go research the truss or get an
expert opinion. Call a local truss company; they have the poop given
the dimensions and construction details...
