^^^^^^^ No need to laquer if solid colour unless as xpackken says you do it in solid clear over base, but if you really want to just make sure paint is dry (make sure it is)then scotch it off & apply clearcoat as long as you key it up properly you shouldn't have any issues with flaking. But you shouldn't need to depends what colour you're painting it if you're goin to paint it in red,white,black or a pastel colour they're usually a soft pigment & will go milky & die, you're better off painting them in cob then that will protect the colour from fading. Being a painter, if funds permit I would always go for cob.
