My plan is to buy aluminum flashing (basically a big roll of sheet aluminum that's very inexpensive and can be cut with scissors - hardware stores in the roofing section) and rivet it in as patches for the open sections. I haven't gotten to doing this part for a reeeaaallly long time and one bummer is that in the trimmed sections the heat has caused the coroplast to curl a way from the heat a little bit and made my belly pan a bit less smooth. The flashing will fix this whenever I get to it.

Just use the aluminum foil tape. Like duct tape in application, its thin foil will dissipate any heat from hot spots better than a thicker material.
