I volunteered to evaluate this product provided to me free from 3M, I am very impressed  with the versatility of this product. It worked well when I applied it to my wall, but would be a great product to overlay on a worn dry erase board to renew the surface. It was easy to apply on a smooth surface with little problem with air bubbles. The surface was very slick and was easy to write on and even easier to erase.I highly recommend this product.
