A big area like a chunk of diamond plate will experience different thermal
expansion from the sheet metal it is covering, because of different
thickness and composition. Eventually, the forces generated will cause any
sealant to pull loose from the plate or from the sheet metal. For this
reason I agree with Mike. If you use a flexible sealer like silicon you may
prolong the time until this happens, but it will eventually pull lose from
either the sheet metal or the plate.

You could try running a bead of sealer along the top edge of the plate to
keep water out, and squirt some in the pop rivet holes before you install
the rivets. This will keep (most) water from getting behind the plate, and
it should let any that does get in to drain out.
