I am going to refinish my kitchen Cabinets and I am going to paint them white. The cabinets are an old dark brown, that I am sure are the original cabinets put in to the house that was built in 1973. I am planning on using a finishing sander and sanding the doors and drawers, the cabinet them selves look to be panneling. What should I do after I sand them down? Please let me know. Thank you, karissa
