i've tried it an it is not worth the money. it honestly didnt even get rid of my slight scratches if you ask me. I got better results using meguiar's regular old cleaner wax when it came to my scratches.
at one point i was driving my old car on a hazardous road and ended up going through a barbed wire fence. that stuff managed to alleviate and REMOVE a good amount of the scratches. In fact i'd say its pretty much capable of getting rid of any scratch that is in your clear coat and it works very well if the scratch is through your color coat but is not too severe
EDIT: and to top it off, you can find it at wal-mart!
