Adjusting Cabinet Doors
Line everything up before you start painting!
Older kitchen cabinets usually have loose hinges, cracks and out-of-alignment doors. Adjusting cabinet doors prior to disassembling insures everything will fit back together when reassembling time comes. You have less chance marking freshly painted cabinets during the reassembling process if you aren't struggling to get things to fit.
