Has anyone had experience with this product? http://www.nichiha.com/pdf/Nichiha%20Product%20Information/NichiFrontier_1.30.12.pdf How does it compare to Hardie---including pricewise? We would be using it only on gables on our house. Our builder uses Hardie products, but we saw this product at a home show today and I love how much like stained cedar shingles it looks! How does it hold up over the long term (no LP type problems I hope!)? Is it necessary to re-stain it over time---how long does the stain hold? Can it be re-stained when needed? I'd love to hear your experiences, opinions and advice...Thanks!
