Thanks but it's not just the pitting I'm wanting to polish them up for, I'm wanting to get that see your face in it high polish effect, I believe you can get a different finish on the metal by applying a high polish to it??
For the pitting so far I haven't tried too hard as I want to do a full polish job on them but I have tried Autoglym Tar Remover, which normally rids most things but didn't seem to touch it, I also tried petrol which also rids most things. Again didn't have much affect.
I'll try the wonder wheels though thanks for the tip.
