What lies beneath!

Lifted the front passengers side carpet and found a damp spot.  Have got to try and trace where it's coming from but have started work on the subsequent rust.  It's only surface so have sanded/wire brushed, then used Kurust and then primer.  That's all I am going to get done today.  If you are checking your Transit pull off the door seal as mine had rusty parts all the way up around the windscreen.

The plan is to underseal any non visible areas and use a blue paint on the step that is a match-ish.
