Been making some more progress throughout the week, here's a few pictures.
Firstly I welded up a couple of the drainage holes as they were quite pitted. Cut out -


Cad template -

Transferred to steel -

Welded in and tidied up (no picture of the other hole welded up as forgot to take one, same thing applies though) -

Then it was on to the mammoth task of cleaning up the floor pan, (I haven't done the boot floor yet though). I sanded it back, treated the surface rust, zinc primed and then applied some regular primer over the top -

Next job was to seal it all up, I masked out where I wanted to apply the sealer so I could get nice straight lines -

Sealer being applied -

Rubbed in and the tape removed -

Same process for the bottom half -


Very happy with the outcome, I'm also going to run a thin bead where the outer sill is plug welded to the floor and also around the seat belt bracket in the tunnel, just for added protection. Will do this tomorrow as I ran out of time today.
Just this to sort out now then I can flip her back over and get started on the front end -
