Corroded rims

[RenfieldFive]

About 6 months ago I took the standard 18" rims off my VF commodore and put some 20's on it. I put the old rims around the side of the house with the intention of selling them. I've owned the car since new and there was not a mark on them ...no curb rash, no gouging ... nothing. They were immaculate. The other day I thought it was about time to pull my finger out and put them on market place. Upon inspection though I can see all these marks on them. I tried autosol, cutting polish etc. but nothing removed it. It looks like the alloy has oxidized. They were fine all the time they were on the car but 6 months storage and they look like **** and I'm baffled as to why. Has anybody got any ideas about cleaning them up ?

Could be Filiform Corrosion, which is corrosion under the clear coat. More unsightly cosmetic than structurally dangerous.

A wire wheel, fine sandpaper and elbow grease were used on a set of polished rims that I bought.
As a DIY, I didn't get them back to the original polished condition, just painted silver and clear coated, and as you intend selling them, cut your profit and sell as is.

Yeah, thought it might be something like that. I'll probably do as you said and just sell them as is.

That happened to the alloy rocker covers and the rims on my XY.

I live near the ocean and the salt air applies a layer of surface rust on every metal object left outside and with alloy that’s the result you get.

It takes an amazing amount of effort to rectify if you are going to try and remove it by hand, as it is pitted and a simple polish won’t do a thing for it.

Whenever I remove rims and tyres from a vehicle for storage and I have a truck load of them, I clean the rims, give them a polish, then apply a couple of layers sealer, then I apply 303 Aerospace protectant to the tyres and finally I buy a 300 metre roll of no-name brand of gladwrap and I wrap and wrap and wrap each rim & tyre in it before I store them.

I can come back to them years later and they look brand new.

Good plan. Trying to rectify the issue will cost more than they are worth. If they are stock VF alloys, which they look like they sell pretty cheap. Under $300 a set I've seen them go for.

Some photos of the corrosion on my XY rims and my start to hand polish it out.

All 4 rims suffered the same fate and so far all I've done is start to rub them back with some wet & dry,

I used 80 grit to remove the pitting which left some mighty scratching, I then progressed through 120, 400, 600, 1000, 1500 & 2000 grit.

That gets the surface nice and smooth so I can start machine polishing to bring back the mirror finish.

It's been a big pain in the bum.

How much for a set of black HF20's ?

That would have been a lot of work to go from a 120 to a 400 grid.
I know, because l used to be a metal polisher.

Earlier in the year l polished my bboss eleanor 19x8 rims.
Masked them up, then paint (clear) stripped them.

Then started with the sand paper. Started with 80 grid, then 120, 180, 240, 320, 400, 600, last 800.
Then got my 4" grinder with a 60 mm extension on it.
Put close stitch mop on it. Mopped all the top surfaces of the wheel with tripoli. Then finished with green rouge.
Tripoli & green rouge are metal polishing compounds.
