Guitar polish/Scratch repairing

Mine is poly-finish and the scratches look like buckle rush(except i dont wear buckles when i play) but wider.I think the bloody gigbag did this:mad:

But i'm asking in general cause one of my friends has an acoustic and another a fender(i think that's nitro) ,all with scratches.
So i saw that clover set in thomann but i didn't find any reviews, although i think there is something on the net but in german:erk:
