I rubbed down my front wings before laquer, i thought they looked good at the time. Then i sprayed my cills and i just built it up gradually and didn't rub down before laquor.
My cills came out much better than the wings, they have a much deeper glossy finish whereas the wings are more frosted looking i.e they don't give a clear reflection like the cills. Ever since then i have never rubed down a top coat of paint before laquor and it's so far always given me an excellent finish.
I guess the type of paint makes a big differance, i find that cellulose based paint is horrid to work with, it wont stick, it runs, it cracks and doesn't give as nice a finish as water/powder based paint.
