Do as Duclover said a few posts back, go to your local hardware and buy yaself some wet&dry sand paper of varying grades , 3 or 4 of each grade and start sanding it !

Start with the lowest grade ie: the 400 grit say. Fold the sheet of paper in half and tear it down the middle, then fold each half in three (this will stop it sliding in your hand) have a bowl of water beside you and dip the paper in the water (wet and dry) this washes any shit out of the grit and wont clog up too quick)

Pick a cover and start working on it, sand until you recon you have sanded all the clearcoat (which is what they spray all over the aluminium cover to stop it dulling DUH ! like it looks worse when the clearcoat cracks up). Then go to a higher grade like 600 or 800 grit and start sanding any scratches the 400 left behind !

And so on untill you try your autosole and it polishes up like chrome !

In some cases you could remove bolts one at a time to get in to the nooks, but remembering they have to be put back in with a torque setting !

If you go out and buy other cases , the chances are they will look the same, soooo ya pay for new cases, then pay for polishing them and then pay to have them changed over (unless you have a torque wrench) and you pay for oil (which will drain out one side) and you pay for gaskets !

Just go pay for some sand paper Aye !!!! Elbow grease is cheap !

so go and get a few pieces of 400, 600 and 800? used 400 first then 6 or 800 to get rid of any scratches then autosol her?

Yeah simple as that !
Perhaps some 1200 as well (skip the 600) alloy sands easy as and any dings or stone chips can be sanded out too, the clearcote will be thin and come off quick, keep the paper wet and splash the black sanding paste ya make away with a splash of water to see how ya going !

I did my front forks outer stauncheons the same way once when i was all keen on bling and shit and they looked like chrome from top to wheel !
Think i started with 2 or 3 hundy and found it was a bit harsh (made more scratches than i wanted) but they still sand out easy !

Oh and the CRC thing ya spoke of earlier works too, i used to spray my whole bike down with it and not wipe it off ! Being carefull to keep it away from brake rotors and pads !
It collects dust of course but it stops the alloy from oxidising (which is the white ya can see where the clearcote has cracked away) but up to you, if as ya say you don't mind using the autosole every now and then, wipe it off and it will shine like a new one !

If you're going to polish them, it's cheap and easy enough to use 400 - 600 - 800 - 1000 - 1200 then autosol
If you use all the grades it's easier to see how good your finish is

Keep the cover clean while polishing, every time you change sand paper, wipe it down and re-wet it

There's an Autosol specifically for alloy, which gives a bit better protection and a slightly more bling finish. Mother's Alloy polish is also good

ill try and go to mitre 10 (??) today after work if I have time, if not maybe some other time this week, sandpaper doesn't cost feck all does it?

**ducatilover** · 22nd January 2013, 14:05

It doesn't cost many fecks at all

When I cleaned my covers up I found a scotchbrite pad was excellent to take the clear off

While on the topic of rapidly deteriorating GNs.... does anyone have any advice for chrome repair? My front guard has a big chip off the front and the metal underneath is now rusting. I keep it well cleaned and oiled but wonder if there's a quick repair or way to "disguise"?

From what I can google, you basically have to get a new part or have it re-chromed?

Also, the exhuast has some "pitting" corrosion which can be improved by rubbing with autosol but I wonder how deep this goes? Some of it seems to come off but not all.... If I keep scrubbing it I'll probably wear the chrome off.

Thanks!

Front guard: clean polish the chip, then clear nail polish on it

Exhaust: scotchbrite pad and autosol

Scotchbrite on chrome will scuff the chrome. Russ Mitchell uses them on all chrome on his choppers, to make it look like brushed stainless. So do I.

Also keep in mind, Autosol is abrasive and while it polishes nicely - constant use will wear the chrome to it's nickel.

$8 later (including a candy bar) I have 400, 800 and 1200. No fecks required

re: autosol u mean the one in the silver box?

Did you get wet and dry sandpaper? It is much better quality in general.
When you send ones wife to get sandpaper, she proudly brings back from Arthurs Emporium, sandpaper that very quickly seperates into it,s two main components, sand and paper!
Really to polish properly, you need to remove. But if you are very determined I guess you can make a good job in situ. Do not be afraid of using paint stripper to get rid of the clear. I polished up my GN spares then sold on TM.
