We are having to install a new security fencing around our allotment.

Its very bright shiny galvanized finish is a bit overpowering. Is there
any way to encourage moss etc to grow on it to get it to blend in more?

The recommended route to encourage lichen for new-build , in
conservation areas , is to slap on, as near as natural yoghurt that you
can find, ie no flavourings/preservatives etc


Strange, in the old days it was liquid cow dung, but then to me there is
little difference.

I use a mixture of moss ground up in the food processor, added to a
bucket of sheep dung, out of date plain yoghurt, and water. Steep
overnight, mix well then slap it on with a wet rag. Speedily promotes
the growth of lichens and mosses (depending on aspect) and an aged look
on raw stone (walls) or clay pots.

but on zinc coated fencing it will just wash off when it rains.

I'm sure I could concoct some mix that will stick to zinc but I
haven't got a suitable galvanised fence to test it!

If you are going to paint with slurry or yoghurt then why not mix in
some PVA glue to help it bond to the zinc?
