Years ago when I used to paint cars with laquer, thinner was available
in several grades, depending on application temperature. You wanted
the solvent to flash off in a reasonable time, not too fast and not
too slow. The grades were generally fast, medium and slow.
Well, you can still get slow laquer thinner, although I don't think
you'll like the price. However, looking up the mds shows it a near
equal combination of acetone, methanol and toluene with the remainder
mostly naptha and a teeny bit of heptane.
You might try thinning that with toluene and/or naptha and see how
it behaves.

A form of silver print is what I used before, it came in
little 1ml syringes. The problem is the solvent evaporates
quickly enough that between dipping the one hair brush into
the paint, and touching the damaged spot, the paint has
skinned over, and won't transfer.
The last time I did it, I put the paint right next to the
damage, and dipped, moved 0.1", and painted. Even with that
small distance, the paint laid down like a mixture of straw
and thick mud, as the crust that formed on the wet paint on
the brush laid down in sheets and strings on the repair.
Got to be a better way!
