100% glop on a dried print will probably be too much and might aggravate the dreaded pizza wheels.  I would try down somewhere around 35-40% and work on up to about 60% for second passes.

I've found on most F type papers a curve that lays somewhere around 80% glop initially and rapidly trails off to zero somewhere by 30% will deal with most of the gloss differential.  If you have bronzing issues then you can try the second pass technique, as I say down somewhere around 35-40 and work up until the bronzing is gone and stop before it starts to puddle.

From following Jon Cone's piezography forum it sounds like they are using dedicated glop printers to lay down the glop in lighter spray from multiple heads to make it even smoother.
