I turned the corner too sharply too close to the curb and my FIT Rear right allow rim was scape /scratched quite deeply exposing about 2 inches of bare aluminum at the edge. Luckily, my spokes are OK

I applied multiple layers of alloy waxing compound (used to polish alloy wheets) hopefully to minimize oxidation of the exposed aluminum.

Any ideas to prevent further oxidation of the affected area, short of buying a new alloy wheel?

Thanks

 

If the scratch isn't too deep just smooth it out with a bit of sandpaper and retouch the paint with a matching silver then apply a coat of clear laquer.

 

There are also companies that repair aluminum wheels. They can repair scrapes, bends, even some cracks! If you don't want to suffer that expense, I have seen some pretty good jobs done repairing wheels with body filler and paint. Obviously only do that for cosmetic problems, not anything structural.

 

you can clean the metal and clearcoat it (just use enamel clear coat, even your nail polish clear will work) or have it repaired at a wheel repair shop.
im not sure where you'd go in canada but in the US there are many wheel repair shops that can match factory paint.

 

If it's a silver painted factory wheel just sand the rough spots and use some bright silver touch up paint.

I got sideswiped in my '09 Fit and was able to make the wheel look decent with very little effort. Actually I don't think I even sanded it. Just cleaned off the tire smears from the other car.

 

Here's a couple of DIY wheel repair links. They may be a bit more than you need to do, but probably worth a look.
