reworking a fully restored car

Here"s the latest pics , first 3 are a series of whats under the shyte ? while scraping some seam putty off where the front edge of the trunk floor is going to lap my screwdriver went through the floor near the passenger side inner wheel house making me think here we go with the next section of full floor replacement but it turns out there is good metal surrounding the hole so a patch will be doable , gotta love how they did a layer of Kitty hair then some sort of blue membrane then another layer of kitty hair .
