I have used an hvlp (high volume low pressure) gravity feed gun for teak oil which is about the same density as the poly i use. Works good but clean up is important or it wont spray good next time. I switched to a regular spray bottle for household cleaners and such. It dont coat as even and nicely or conservatively but speeds things up a lot. Very nice work and precision on the casket. Would be a shame to just bury all that hard work.
