Well - yes and no. Lacquer will burn into itself, but that is best relied
upon when the stuff is in flash, and not after a full dry. Since the OP
waited until the coats were dry to apply the next coat, I would at least
scruff it. There is a risk of edge lifting when applying over dry coats.


Some catalysed lacquers (certainly most automotive ones) don't melt
into themselves that well.
A scuffing would give it 'tooth' and de-glaze the surface.
Nitro-cellulose lacquers, even the mildly catalysed ones, will respond
to a 50% thinned blast of lacquer , instead of a scuffing.
The simple test, is to apply some thinners to see if it softens the
existing coats.
If it is a catalysed lacquer and you spray it with a full-strength
catalysed lacquer, without scuffing.. the edges WILL lift... very
visible on 32 dark stained cherry(shudder) doors. DAMHIKT. (We had to
sand everything, right into the nooks and crannies of raised panel
doors...2 guys, 2 days. Then re-stain the sand-throughs, feathering,
re-sealing, then fight the farking fish-eyes...at least a $ 2000.00
problem)

Always test with thinners.

I agree that the best results are wet on tacky... after a flash-off
but not dry.
