It's all about the scratch innit...!!...only a fairly light surface scratch will respond to the varous remedies available. (I use G3).
It's possible to "improve" the look of some deeper scratches but it will be temporary.
I always use the finger nail test...and if you can feel the scratch with that then usually it's time to look for more professional help if you want scratch removal.
Depends what you can personally live with surely.?
I normaly polish over the scratch untill I can get someone to do it, I used one once and it was the last time, it was useless but expensive at the time, if scratch is tiny I will live with it or try and T cut it out which often works
