Wet sanding

[Niall]

Tom a polish (or compound like he's used) is basically a liquid sand paper but where as he's used 1000 grit paper, polish is usually so fine you could probably compare it to something like 7-10000 grip paper (if it existed!)
This is why you can't cut a car too often because eventually you will take the clear cost away completely and then it needs to go for a repspray
