I cannot recommend a particular consumer product, however, I have some experience with producing thin transparent films. A paint or coating is very unlikely to be transparent after it has been applied to a glass surface, without special treatment, such as spin-coating. An unevenly coated surface will be translucent, allowing light to pass, with no coherent visibility through the glass.
