what sparky said. doing it without a powertool will take ages.
I have grey and blue, I think. The colours denote the Grit size. They came in solid blocks, like Plasticine, and you rub some on the powertool attachment, the mop. I am sure sparky will know more, especially regarding UK brands
How rough is it Paul?I'm only asking as if its bad you might have to start with some fine wet an dry then work up the grits to the compound
I would use a stitched mop and some grey compoundSomething like these...http://www.axminster.co.uk/polishing-mops-stitched(I would try putting a 6mm nut and bolt through the mop )http://www.axminster.co.uk/grey-polishing-compound-supercut
