I'm trying to refurb a set of flat faced polished wheels,been rubbing them down for what seems like ages,solvol doesn't give me a good shine, there is a wee bit that is shiny ner the front of the pic,but i cant get the rest anything like it! the inserts of the spokes are gonna be gunmetal,but did want to have at least a decent shine on the faces,  where am i going wrong? the offending wheels  where am i going wrong? cheers scott |

I would be using 800, then 1200 then 1500 wet n dry, preferably in a power sander like a black&decker Mouse kind of thing, then once done with the 1500, I would then move onto the polishing compound. Its a hell of a lot of effort.

my advice is pay somebody else to do it  the only way it can be done is by the above. either that or have the faces machined, would cost though, although it provides a damn good look |

You need some polishing mops to finish it off. Machine mart do a set that would do a set of wheels and fit a normal drill. like thisGive you a shine like these spokes, Sanded as you've done,  Then mopped,  and the finished wheel, BLING!.  |

As was said before, finer and finer grades of wet and dry but down to 2000 grade. Then finish with solvol and a drill powered mop. Some i did earlier...........   |

You'll never get them shiney if you didn't start with a rough enough paper in the first place.
Depending on the condition of the surface in the first place,i'd start with 240 grit if not too bad or 120 grit if it's pretty bad.
So go 240 - 400 - 800 - 1200 to polishing compound

I wouldn't do them with a power sander, the motion of them leaves hard to remove scratches in the alloy.
I do most of the work with 240 grit, then 400, 600, 800, 1000,1200 and 1500, then finish with polishing compound on a mop, then autosol on a mop.

For the cosmics I went 240 on a DA to remove machine marks or casting pits then 600 and then 1200 both by hand then the mop with a proper polishing soap.
Did all four wheels in about 5 hours + paint.

Yep I'm afraid that elbow grease is the only way forwards matey. I did my turbines in the lathe and polished them by hand with them spinning, makes life a lot easier but still an absolute ballache. I went from Nitromors, 80g, 200g,400g, 600, 1000, 1200g and then autosol. This is one prior to autosol, they are mirror finish now !  |

ages ago i polished my motorbike wheels.
to take the paint off i used a scotchbright wheel on an electric drill and then worked through the 3 mop and compound sets to provide a very nice mirror finish.
only snag was using the bike made the rims dirty very quickly!

i've done a few sets of wheels and a few engine parts and find the best way is to use the methods everyone else has suggested, but after removing any paint, use a lubricant like oil or t-cut, fairy liquid, any thing other than water. go through the different grades of grit ( i only go to 1200) then use autosol to finnish with a mop, this a messy proccess but a good one. hope this helps.

i agree with the above, although some typres of alloy will never come up that well when polished, simply as the alloy isnt the right type, forged alloys seem to come up the best (ie porsche d90, 928's etc) as the metal grains are packed together more tightly. but I'm sure yours will come up great with a bit more elbow grease  |

I wouldnt advise to use washing up liquid as it contains salt and if you have bare metal roll on the mice
