I think this greatly improved the look of some old snaps, and even helped repair and make a crack look less nasty after I applied glue to it. Helps with minor scuffs and scratches too! Does it look like glass? Well, sometimes, maybe, from some angles... but it sure helps! Mind, I haven't tried any competing products, and this is not a horrible price I think in this industry for speciality products. Recommended for a first foray into glass-like enhancements on basic car windshields, at least in my limited hobbyist experience.
