Hmmm... I've just realised that everyone seems to be assuming that the
sill is still porous. Don't forget I have given a very generous sloshing
with silicone fluid. I WAS hoping you'd all say that should be OK, but
the only comment on is from Andy saying his only helped a bit. Is it the
case you all think that stuff was a waste of time?
'Fraid so. These products are usually siloxanes which, unlike silicone,
don't form a continuous film. They cure as microscopic pellets of
grease/rubber which can be dislodged by (although not soluble in) water.
Same stuff they use for dpc injection I think.
