   I only use 320 grit to scuff sand between coats of lacquer. Finer than that and it takes too long. Courser than that and sand scratches don't cover as well plus it's a lot easier to accidentally sand thru with courser grits.

   Will, haven't you got a compressor and spray gun? Fer the loooove of the Load, man.
   If you must use that can spray I suggest you put on a good coating of something like Zinzsser Bulls eye shellac sealer first, sand it flat and then use your canned stuff if you must. Rub the horrible canned stuff down with fine steel wool and stay away from the sand paper.I tell you I also hate sandpaper and always focus on minimising it's use-have you noticed how expensive the decent stuff has become over the years?An half the time it is thrown away because it is torn, or clogged, or not fast enough, or used dry when it is better wet-anything other than worn out.
   Next time you are knee deep in 1/4 sheets stop and count them and see what it cost....It's all part of an evil plan hatched by 3M and the boys...

           Hi Will ,

                       Some lacquer finishes utilize lacquer sanding sealer first , then top coats of clear lacquer . Sanding sealer is much softer than the top coat of lacquer . On a very small project a rattle can may workout , but on a mid or good sized piece a spray can may prove to be a futile avenue to travel .But , as far as sanding between  coats I use worn out 220 silicon carbide A wt paper . It is probably similar to say 320 grit . For the last 30 years it has never failed , to help in producing a fine finish . Partly the reason to sand between coats is to knock down the buggers and such that typically rise up with the first coats . The other reason is to aid with adhesion from one coat to the next .

                      good   luck     dusty

   I've used Deft lacquer with mild sanding between coats to flatten: either 220 or 320 is fine.  With nitrocellulose lacquer, each coat will dissolve the undercoat some, so you do not need to sand for adhesion, only to flatten.

   I find the abralon disk pads are great for working lacquer up to a good gloss.  You can find them at homesteadfinishing or woodworker.com.
