John,all,
Water based will absorb about the same as an evaporated finish(shellac,
laquer)The curing of water-based finishes mixes the
crosslinked(varnish,polyurethane,catylized finishes ) and evaporative
finishes.They're basically small droplets of partially cured finish( imagine
soccer balls of resin) As the water and solvent evaporate the balls come
together and coalesce.Water can't get thru the balls but it can get between
them.I'm gonna try pre-catalyzed laquer.
