All the professional Mini body restorers I know would never, ever fit those dreadful oversills.
Best to cut them off, cut away all the rust underneath and do the job properly with correct sills, etc.

Correct me if I'm wrong- but inside the pockets either side of the rear seat, there is a panel that sort of closes the gap between outer and inner sill, which is actually slightly open- so whats all this talk about condensation having nowhere to go with sealed sills?

I've used the wider sills on mine, though I cut them down to about 6" from the original 9". Seam welded all round, of course I removed all the rusty old sills first and primed the inside of the inner sill again after removing surface rust, I'm also planning on drilling a hole in either end so I can insert a long waxoyl probe and fully cost the insides, and it means I will also have removable bungs should water ever somehow find its way in there.

I think whichever way you look at this oversills are frowned upon and were only ever meant as a repair panel to get a car through an MOT. Even with the open area of the companion bin, side panels and the bin cover will still let condensation build up plus no matter what vehicle you are in condensation builds up. We suffer it on aircraft due to the extremes in temperature.

-50c at altitude and then temperatures up to +50c on the ground (Dubai) condensation builds up like you would not believe. Although a mini does not suffer these extremes of temperature due to the humidity in this country mositure still works its way into the smallest/enclosed of spaces.

The answer is use the proper sills, paint them, fit them, force more paint in then pump it full of waxoyl, happy days.
