I'd give it 0 if I could
...RUINED my windshield.<br /><br />Instructions state to apply it with a sponge for 30 seconds, then rinse with copious amounts of water.<br /><br />Nervous, I only did 10 seconds (very hot day, was afraid it would evaporate and leave residue).<br /><br />...no residue, instead it looks like it scored or etched the glass.  Now I'm out a windshiled.  Would NOT suggest ANYONE use this product.
