If you move on to the next grit paper level with the pitting still visible it will always be there. You only move on a grit level to remove the scratches that the previous grit paper left not to remove pitting or original imperfections

Have not read this entire thread so forgive me if this is old ground and it may not be how everybody does it :thumbup:



So i have to keep sanding longer with 120 grit? till the pitting got away and then move on to the next grit?
I'll try that if I'm home from work :mrgreen:


Thanks man :thumbup:



i could not have put it better!!

What kind of machines do you use to polish the wheels? Do you have any pics? What do I need to get to start a job like this?

I have polished many sets of wheels as well as many other materials. At 1st I used the sandpaper route going from 120-2000 and then some kind of finishing rouge. This proved to have good results but took a long time and required a lot of muscle.

IF your wheels are not pitted you can do the entire process with Greaseless Cutting Compound (the compounds come in different grits from 80 to 600), a drill with cord that can run 3,400rpm to 5,000, an arbor adapter for the drill, some spiral/Sisal Sewn cotton Wheels and bobs, some finishing Tripoli and a fine polish of choice, I like to use FLITZ METAL POLISH.

When you buy your drill get one that has a trigger that can be locked so you don't have to keep your finger on it for those long periods. Flexible extension can be had on the cheap (I highly recommend one). If you have a grinder I have seen special extensions made just for polishing. I will buy one soon and report back on that.

Once you try this method you will never go back to wet\dry again.

Remember, once you start at a low grit you will have to work your way up through the grits, so I suggest starting with180 or 240 and test out how it looks. From the results of the test you can go up or down in grit.

Also, make sure the aluminum is does not have a clear coat on it or you will be spinning your wheels. To test take some aluminum polish and polish a small area, if the rag turns black then you are down to the aluminum, if it doesn't then it is cleared and you need to remove it before polishing. I use aircraft paint stripper as it is fast.

On the wheel above, I would go at it with some 180 grit compound and a spiral cotton wheel, you will be amazed at the outcome and the transformation is almost immediate.

Hi thanks for the reply voyd

I just carried on sanding down the alloys from 80-2500 ( i know i didnt need to go that far) was my first attempt,then i got a drill and a mop,and used the white compound,and i was suprised my self at the finish,cant really show the reflections in this pic as my phone camera isnt that good. i think i need to get some metal polish now,and that should be enough..

Hi lads,
I'm new to polishing alloys,iv done a set of pepper pots and came up a treat,
Image
Now iv started on a set of A3/4 wheels and can't get any better than a dull shine
Image
Is it that it's a cheap alloy or that it's a cast alloy,iv used the same grit and polish,it's just not happening.
Iv worked up to 2000 grit,autosol,mothers even old car polish.
Should I just paint them.
Any help would be great.

I don't think that will work,I went and got 4000 grit and finished with mothers billet and it was no better. I'd say it's whatever was used in the mix to cast the aluminium.
So next question can all alloys be polished to a mirror finish?

Did you test the rim to find out if there is a coating on top of the aluminium?
