Wish I had a pic to show but KOW no scratches. I have seen pics though and what the Langka product does is it smooths out the touch up paint which usually leaves a bump or a raised area around the blemish. Its by no means gonna make it perfect again but it does help the touch up paint look better.
There were quite a few people that used this product over on the PT Enthusiast web site. You might want to take a look over there and punch in Langka on their search engine. I have some and like I said I've never had to use it.
