^^^This...I replaced some bench seat tops and made removeable floor sections with good one side plywood and covered with vinyl decking, all bought at Home Depot. I also sealed the exposed wood underside. After ten years the vinyl still looks great and it has had a hard life.
I would NOT use regular plywood under flooring that was permanent and could not dried out tho, marine grade for that application.
I would think spray in boxliner would add too much weight?
