1. An anti-graffiti surface coating consisting essentially of the combination of:
- alkali metal silicate;
ethylene-glycol colloidal silica;
aminopropyl oxysilane;
fluorinated polyurethane; and
alkali metal methyl siliconate;
the coating characterized in that it is a surface-penetrating coating, is chemically resistant, and possesses a surface tension higher than the surface tension of the surface to which it is applied, whereby paint applied to said coating is easily removed.
