I noticed an apparently new product at local supermarket. It is
labelled specifically as a general lawn fertiliser.

And it appears to be made entirely from fish emulsion (basically
waste substances from rendering fish for food.)

It is a concentrate, where you would mix a capful with several
litres of water, and apply with a pump-sprayer. It isn't clear
if this is supposed to absorb through the grass blades, or if it
is meant to soak into the soil.

Has anybody used something like this?

BTW, my current plan is to apply cheap generic granular
fertiliser every three months, plus lime once per year.

Also note that my yard is in bad shape, and I have started some
aggressive overseeding ('scuse me while I go out to water it for
the third time today...)
