This is a good product. It protects my table and is superior to the piece of marble floor tile I was using. A note, Tamiya Thin cement will remove those lines, the angles, marks, etc. It does this quickly. Other than that, thin cement or thick did not permanently adhere and any paint has came up. The surface will scratch. But I do not bear down that hard when cutting so this was a very good deal for the price. That said, I want to move up to the larger green mat. I have butchered a lot of plastic, wasted paint and am ready to inflict myself upon a small diorama. The 80 mm mortar will be my first. I will assemble it on this mat. John and when I learn how to get my pics out of my phone I will download them.
