Aluminium rims preparation/repair

Hello, would like to try it yourself and bring my rims on high gloss and fix curb scratchers. I would like to ask the forum for experiences and tips on how to do the best and which mediums are good and which should not be purchased. I just want to grind the scratches and make them smooth where necessary with such a paste damage. I will pass the painting on to a paint shop. Felge looks like this:http://www.hood.de/img/full/2135/213553 186.jpg This is not mine but has similar damage on the edges. I’m only concerned with the edge. The rest still looks top.
