Does anyone know if paint thinner can be used instead of lacquer thinner for metal
surface preparation before painting? Does paint thinner leave any surface film? (Pain
direction says use lacquer thinner)

^^^^^^^^^^^^^
If the metal is CLEAN, it should not need any solvent washing prior to
painting I spray paint steel all the time without washing it. Most things
that might interfere with paint adhesion, like wax or oil, would be removed
by either paint or lacquer thinner. Silicones are hard to remove, and I'm
not sure even lacquer thinner can do a good job.

One of the tests done to determine if metal is clean is a water break
test. You just put water on the surface and if it beads up, the
surface is not clean. If it stays in one continuous sheet, the metal
is clean.

Naphtha is one good remover of silicone and many other oily
substances.
