Pretty much this.

I followed this thread years ago:
https://cbrforum.com/forum/general-t...ng-rims-12673/

Only difference was I applied aircraft remover, wiped off, very light steel wool sand to get some residue off, some Mothers polish, and still got this:

 

Thanks Anythony that looks great! Are the rims smooth or do they still have the little grooves in them?

 

Thanks! Rims are smooth!

I guess I was pleasantly surprised on how they turned out. Thanks to it being the summer now, it should be ideal conditions for the aircraft remover to do its chemical reactions. I did this in the winter time, and it took longer than expected to strip. Otherwise, tape off what you don't want stripped (I taped off the inner center of the wheel), aircraft remover, let sit, wipe off with a rag (light steel wool to rid of any stubborn sticky residue or reapply aircraft remover to these portions), metal polish, and bam! I recommend:


If you want even MORE shine, you can do the additional sanding route. After I stripped, I found the extra sanding to be completely unnecessary for my tastes. This was plenty polished and shiny for me.

 

Thanks man!

 

What's the vest way for me to get out the black marks I have on my rim? Its already polished, that's how I nought my bike, but I want to get rid of the black marks and re-shine them

 

By the way here's my rims in the sun so you can see what they look like

 

Is that road tar/dirt? If so you can try power washing and light steel wool sanding, then metal polisher.

 

I'm not exactly sure what it is. I tried scrubbin it before but it wouldn't come off

 

Hard to say.
Judging by the second pic, when you bought the bike it was already nicely polished and after some use, the black marks started accumulating?

Or if the black marks were already there, maybe the prev owner didn't do a good job stripping the original coat.

 

Yeah they were there when I bought the bike. There's a lot on the side with the chain. So do you think They might have over lubed the chain with somethin and that stuff stuck to my rim?
