I have installed several cabinets in my carport and want to place a countertop of some kind across the top of them. Although the inside of the carport is not exposed to rain, it is open in spots thus the moisture in the air is a factor. I have considered (1) a premade laminate counter top or (2) make one myself of high density particle board or 3/4" plywood covered with a laminate. The size will be 2 ft x 8 ft. I am looking for opinions (potential problems) on what I am trying to do, or solicate the "better idea" if possible.
