When I lived in Washington my plywood place (Midway Plywood in Mukilteo) sold MDO (medium density overlay) or signboard, a high quality 3/4" plywood with a tan or light brown phenolic laminate on both sides. Very durable and weather resistant. I am looking for a supplier in Logan but haven't been able to find any. One builder's supply place has HDO, which is normally used for concrete forms, I believe, but the coating is a whitish color, and printed on the back side. Anyone know of a source of the tan MDO in the Ogden/Logan area?
