pol doesnt have a high adhesion property cause it sits on the in layers when laq soaks and each layer dissolves into the one under it
poly doesnt scratch as easy
laq dries faster
laq has a more refined look IMO you know they have make a commercial blend of the 2 now that stuff is great all the pros of both finishes witout the con except the price lol

If you are looking at a great finish with the burn-in properties of lacquer and a tougher finish then poly, take a look at conversion varnish (odor similar to lacquer). It is a two part solvent based finish that dries very fast and is considerably more durable then either lacquer or poly. It is the only thing I will use in cabinetry.

Lacquer is a burn-in finish with a final thickness that is less per coat then poly. As cabs4less says, poly is a film finish that layers on top of the previous layer (tougher to repair). 3 coast of poly is thicker then 3 coats of lacquer.

You can get water born lacquer – I have tried it with limited success – that doesn’t have the smell of solvent lacquer. A water borne poly (little or no odor) will dry pretty fast enabling you to complete 3 coats in a day without any problem. The conversion varnish enables the same thing – 3 coats of finish in one day.

Poly hides scratches better because of its flexibility. It can expand and contract more then most other finishes.
