Using por15 on those areas you wire brushed would work great. For the exterior, welding in a whole new rear piece would work also.

I would recommend this welder-

I have a alpine trunk lid in great condition if your interested? It also had the hole for the "is" spoiler but I can't seem to find the spoiler. Pm me if your interested.

Trunk lid is rust free. I do, however, need an entire rear section. Any one know a precise way of cutting one out?
