I need a step by step for refinishing 1950's era kitchen cabinets. They seem to be solid enough wood for sanding with a random orbit sander. They are faded with water spots and some crackling of the finish in places. I'd like to sand off the old finish and restain a darker more contemporary color. They are very solid and have a lot of character. Never been painted! I love them and want to bring them back to life. Any suggestions would be greatly appreciated. Thanks!
