I would see if you could get them to stain it before putting it up.
Or, maybe they have some airless skills and don't mind sanding above their head for 20-30 minutes at a time.
Alcohol toner, light sand, stain, lacquer, lacquer, lacquer all applied airless to make it deep and pretty.
Or home depot behr deck stain. Preferably a dark color hand brushed to make sure the lap marks are as thick and visible as possible. Did you look away? That's a lap mark. Would you like another? Would you like another?
