The invention relates to a substrate marking system. A marked substrate including a solid substrate surface such as, for example, a road surface having disposed thereon a first coating including a pigment and a first binder polymer, the first coating having a dry film thickness of from 10 microns to 5000 microns; the first coating having disposed thereon, a clear second coating including from 75% to 100%, by weight based on the weight of the clear coating, nanosilica and from 0% to 25%, by weight based on the weight of the clear coating, second binder polymer; the clear second coating having a dry film thickness of from 1 to 10 microns is provided. A method for providing the marked substrate is also provided.
