    A huge advantage of using lasers is the properties won’t rub off. Imagine your favorite frying pan. The water resistant properties wear off over time. But, since “the structures created by our laser on the metals are intrinsically part of the material surface,” according to Guo – it will never wear off.

    I wonder if with heavier use or damage (dents, scratches, etc) the water resistant properties would cease?
