Press the Z-poxy into the pores, allow to dry overnight and then sand with 400 grit paper. Apply a second (or third)coat until you have a perfectly flat surface. The last coat can be thinned with alcohol and wiped on with a towel. The alcohol will evaporate leaving a glassy surface. Be sure you do NOT sand to the bare wood when sanding. Then finish with KTM9, de-waxed Shellac, lacquer or urethane
