alloy wheel corrosion

[discolaw]

Hello All
The alloy wheels on my D2a are suffering corrosion from brake dust etc. If they had a protective coating its gone now (bought 2nd hand). Has anyone found a product/coating that restores some protection. I'm not talking about wheel cleaners but something that means you don't feel the need to clean so often.
Also can these wheels be polished/buffed like ordinary mags to help with this common problem
Cheers

Yes they can be repainted or even metal polished and clear coated.
Brake dust eats anything.
Once repaired use a spray cleaner and hose once a week.
