Had a go at repairing cloudy lights ?

Hi guys, I seen on here a lot of guys were doing the old sand down and polish up method so I thought I'd give it a blast, I had some really really smooth sand paper lying around as fine as you can get, I started sanding down the drivers side light, after about 20 minutes or so it looked a lot better but obviously very foggy, the only polish I had lying around was autoglym super resin polish so I used that for about 10-15 minutes on it but there's still loads of slight scrapes on the light, to look at them now the drivers side looks clear and the passengers side looks yellow but is there any way to remove the slight scores I've left on the light, will I need to do it again or use a better polish?
