Time to spot weed my lawn to get rid a few big ugly weeds.

I have an industrial quantity of concentrated (not farmers superconc,
the next one down) generic glyphosate.

Any suggestions what would be a good admix to make it more like a gel to
paint on the leaves?

Don't do it. Grass is exquisitely sensitive to glyphosate and you will
end up with big ugly dead brown patches. I knew someone who tried to do
the DIY spot weeder trick with "Pathclear" and it was the devils own job
to repopulate the damaged areas with grass again.

It wasn't the glyphosate - it was the diflufenican (or whatever emergent
herbicide was in an older formulation). That, by design, hangs around
for months to kill anything emerging through the soil.
