Abstract
Certain example embodiments relate to a coated article including a coating formed from a sol that has hydrophobic surface properties. The sol may include a mixture of at least two alkylsiloxane chemicals, with the sol potentially being aged for a certain comparatively short amount of time before being wet-applied to a major substrate surface. The application process may also undergo a certain comparatively short curing process to help provide hydrophobic surface properties. The hydrophobic surface properties help provide anti-soiling functions that are advantageous in a variety of applications including, for example, solar mirror applications.

1-28. (canceled)
A method of making a coated article comprising a glass substrate supporting a coating, the method comprising:
- wet-applying a sol, directly or indirectly, on a major surface of the substrate, the sol comprising at least first and second alkylsiloxane chemicals, the first alkylsiloxane chemical comprising tetraethyl orthosilicate (TEOS) and the second alkylsiloxane chemical comprising a siloxane other than TEOS, wherein the TEOS and the second alkylsiloxane chemical comprising a siloxane other than TEOS are provided in weight percentages in the sol that differ from one another by no more than 5%;
- and
- drying and/or curing the sol to form the coating, the coating having a root mean square roughness of 3-6.5 nm,
- wherein the sol is aged for no more than five months prior to the wet-applying.
