Scratch remover doesn't remove any scratches, instead makes shiny surface of your car dull after applying it. It removes top coat of shiny layer from your car paint. The Polish is also totally useless, does not provide any shine. Never buy this crap. Go for some branded ones
Believe me the scratch remover product is just worst. Rather it faded the shininess of a surface on my new scooty. I tried to remove a small scratch on a black shinny surface of my scooty, what it did is just fade the colour of the surface and made thousands small scratches on that surface so that the the main scratch become less visible.. But it works (10% only) on matt finish surface because imatt surface do not shine.
The lather polish is useless too. (30%) effective.
