[TR] TR2 sill / bulkhead sealing

Hi all

Finally after 40 years driving I am getting the sills & floors on my TR2 
replaced, currently at the panel beaters having them welded in. So my 
question is:-

How to deal with the dirt & moisture trap made by the "box" enclosed by 
the bulkhead & sealing plate at the front, the 'A' pillar at the back, 
the sill & front guard (fender in USA) at the bottom, & the rear of the 
inner guard etc at the top.

We all know that the factory sealing plate & rubber seals at the front 
are meant to stop the road dirt & moisture getting in, but don't do it 
very well. Then when it rains the water comes in between the side of the 
bonnet (hood in USA) & the front guards onto the top of the inner guard 
(fender), plus at the rear end of the bonnet it runs down from the 
gutter at the front of the bulkhead into the gap at the rear of the 
inner guard which is cleverly angled so that all this water drips off 
the back end into the above mentioned "box" enclosure where it combines 
with the road dirt etc and eventually rots out the front of the sill and 
the side kick panel in the cockpit & then the front of the floors.

General consensus seem to be that we should remove the bulkhead sealing 
plates each year and clean out all this accumulated 'crud' and dry out 
this area before replacing them.

Has anyone come up with a way of draining this area so it doesn't stay damp?

What is the consensus on the best treatment of this front part of the 
sill and bottom of the inner side of the guard etc. to stop rust 
attacking it?

All suggestions gratefully received.

cheers,

stay safe,
