As an experiment we are replacing a nominally 6' by 6' fence panel (blown
out in the gales, bottom rail rotted away) with lengths of 6x2 laid on
their side.

So that would be 12 lengths of 6' long 6x2 all laid on the side and
stacking up between the concrete fence posts.

We did similar with concrete gravel boards for the first two panels by the
house, and this has worked well but we aren't keen on a 100% concrete look
all the way down the garden.

So we have these 6x2 lengths, with one 2" side down and the other up.
The gaps are where water collects and rot sets in over time.
Any recommendations about what to put in the gaps?

Could be silicone sealant, could be black mastic or some other kind of
sealant which would fill the space and repel water. Could be in a tube for
"gunning" in or in a pot to paint on.

[This could also be a strategy for fence panels, which only last about 6
years before the bottom rots away.]

The nice thing about this strategy is that you can fit the lengths of 6x2
one at a time, instead of the usual game of holding a 6x6 fence panel up
in the air in a gusty wind to get it over the top of the 6' concrete posts.
You should also be able to take it out again and replace, for example,
just the bottom one if this has rotted.
