Looks like I'll be taking my sills off later in the year as the front and rear trailing edges are just starting to have a bit of rust forming. One thing I was thinking of doing after refurbing/replacing the sills was to seal off the gaps with a few layers of Denso tape. For those who haven't heard of it, its used in industry to protect carbon steel fittings in exposed/extreme condition locations. Back in the 70s we used it at ICI out on the chemical plants and more recently offshore on oil installations/platforms. It really does stick like s**t to the proverbial blanket.!!!
I have some rolls in the garage from way back which I'll be using, but I've just checked online and its still available see link below, there will be other locations to source it if you do a search to get the width you want. Its available in 50mm, 75mm,100mm & 150mm wide rolls x 10mts long, so one roll will go a long way. The advantage is it sticks really well to surfaces without any mechanical fixings just press it in places and remove any air bubbles towards the edge and it self seals. I suppose if you wanted you could apply a coat of underseal to blend the colour in with wing liners etc. Wear some disposable gloves to apply and don't get it on your clothes!!

Hi @petecossie ..... wondering if you used the Denso hack? If so, how did it go? Did it work? Did it trap in any moisture causing unintended consequences? and.... did you paint the Denso with underseal (looking at online images its pretty ugly stuff!) and if so did the underseal take well?

Questions, questions, but having just checked and cleaned the inner sills, your Denso hack sounds like an interesting final finishing point....... and I'm wondering how it worked out, and what are the results over the passage of time ??

Yes I did use the Denso tape to seal off the area at the bottom of the wheel arch liner and protect the leading edge of the sill (see attached photos) I also used it around the jacking point pads.
Can't say how effective it has been as I don't want to disturb anything, however it all looks good as far as I can see. Knowing how this stuff sticks to the any surface and protects it from using it in the oil field I'm sure it works OK.

As you can see from the original setup of the jacking pads before I removed them, sealing round them would stop water encroachment. Unfortunately I haven't a piture of the final pad attachment.

Don't forget to get some jacking pads from eBay.
