Question: can dry erase markers be used on laminated paper?
Answer: First, don't use dry erase pens, use wet erase (aka overhead projector pens). These dry quickly and don't smudge. When they need to be erased, a wetted paper towel works great. Just be safe, you can use plexiglass or acetate (a clear thin plastic sheet that can be rolled up) to pretect the board.
