Sorry its regarding wheel lips lol. Ok thought I'd Share my hard work with you lot.
I embarrassedly curbed one of my wheel the other day. with deep stuffs 1/3 around the wheel. I was so pissed off I had done this to my recently purchased wheels I didn't take a pic for a before and after job.
I had refurbished my old wheels quite well so I was rather confident I could do this, however as my old rims were...old they didn't have a mirror finish so this would be the next level up of a challenge.
I used a VERY coarse sandpaper to get rid of the deep scratches and dents. Then use wet and dry in 240, 400, 800, 1200, 1500 grades. Then use more 1500 with Maguires metal polish as few times then alloy wheel seal. A real pest to do and alot of hard work but VERY much worth it to get it as good as you can get.. Some more weight off my mind..
Here is a few pics of my wheel I refurbished (excuse the dirty car lol)
