The interior of the trunk, as seen as it was opened for the first time. Note the original battery tray, with the black anti-corrosion mat, but no battery installed. The hub caps seen in the photo are not Lotus Cortina parts, just trash. The original jack (painted grey- but looks blue-ish-grey in the photo) is also seen. The battery tray and surrounding area had some light surface rust, but no "worm holes" whatsoever.
This is the underside of the battery tray area- note this area had no paint or rustproofing coating on it at all. The light surface rust seen cleaned up with no effort at all!
And here is the tray itself, after clean-up, glass bead blasting, and respray.
