Lamborghini Urraco rear floor rust proofing

Decided to tackle the ugly (but solid) rear floor area. As you may know it has the at factory sound deadening material and then insulation on it. The original tar material has lifted around its edges so it needed to come off. It's hard and brittle so chipped off quite easily.

The floor is solid with a little surface rust from moisture where the tar was not. Cleaned up now and painted with rust converter paint then waxed around the seams. Also waxed inside the chassis floor cross box section that separates front floor from rear. The car will never see rain or damp again so that's how it will be now forever - next job is the other side then the front floor areas.
