I want to polish an old rocker cover up, but I'm not sure how to do it.

It's quite tatty, so I'm not sure metal polish would do it to start with?

Would I be best going through the wet and dry paper grades gradually getting finer til it was ready for the polish?

Has anyone done it before by hand?

Ok, I've been told to use 600grit, 800grit, 1000grit, 1200 grit and 1500grit, in that order.

Can I find anything finer than 600grit anywhere?

Can I balls

I think I'm going to have to use the 600grit then some Peek, it that'll do it?

I might just break in to my old school and use the buffer in the DT block

Yeah, I got 600 grit from B&Q earlier, but couldn't get anything finer, I went to B&Q, Homecase and Halfords (they're the only places near me who sell it) and none had anything finer than 600

Sorry, mis-read it.

How fine do you need it to be?

Well, I need 5 sheets of 800, 5 sheets of 1200, I think that should do it.

I've looked on ebay though, it seems I can only buy 50 sheets of it

Rob, Halfords should stock right up to 1200 grit. Maybe you should just wait and try them again later in the week?
