My first job after graduation from high school in 1971 was in a custom kitchen cabinet factory, Wood Mode. I started in the staining dept. All hardwoods were sprayed with water using airless guns. This raised the grain, allowing stain to penetrate deeper. Pine was never wet as it would cause blotching. Stained pieces were sprayed with sealer and sanded with 240 grit. First coat of lacquer was sanded with 320. Finishing coat was wet sanded with 600, then 0000 steel wool before waxed with Johnsons floor wax polished with sheepskin pads. I still use this process with water borne finish excepting conditioning pads rather than steel wool.
