Unfortunately managed to scuff my rear left wheel yesterday.

Not bothered enough to replace the whole wheel but wondering what my options are? It looks like it's taken off some kind of coating layer and I'm wondering if it can be repaired easily? Other than that I guess I'd just want to make it less noticeable, any ideas?

For reference they are these wheels.

Thanks.

:(I hate alloys. Why are they magnetically attracted to kerbs?
With yours being diamond cut, a proper fix is the only answer, else the dreaded 'white worm' will take hold.

Get some clear lacquer in a touch up stick, that will stop salt getting in and eating away at it.

Had a lease for a couple of years and kept them pretty much scuff free, but a few months after I buy my own car... ?‍♂️

By proper fix you mean I need to take it to a professional? Or would some touch up lacquer work as Jase suggests?

Any suggestions for brand/where to buy?

This happened to me the other week, I did a DIY fix.

Start with 400 grit sand paper, move up to 600 and then wet sand with 1200 & 2000. Polish and then lacquer, jobs a goodun!

Nice job Sochaux.?
Did a similar repair on mine a few months back. My results weren’t perfect but unless you really study the alloy you can’t see it. ?
Can only see the repair in a certain light it’s very slightly a darker shade.
I did spray the lacquer on after masking the area off. Got a better finish. Found that when applying the lacquer with a touch up brush, I could see the brush marks?

Perfect, that's exactly what I was thinking of doing. Are you able to link the lacquer you used? Did you spray it or brush it on?

I bought a can of lacquer from Halfords, sprayed it into the lid and applied with a very small paint brush.

I was extremely happy with the finish considering I’m only 4 months into my lease and now I’m not as annoyed at myself!

Ordered some sandpaper and lacquer, will update with results once I'm done.

I used a polishing attachment on a drill with some AutoGlym resin polish, came up nicely.

+1 on the Halfords lacquer. Seemed to get the job done for me as well?. Just go easy on the wet and dry. Don’t try and take too much off in one hit.
It’s worth masking up where you don’t want to sand, prevents you sanding areas of the alloy which are ok.

Sanded down until the dirt was gone and then lacquered. Still visible if you're looking for it but much less noticeable overall so reasonably happy.

Same part as first post:

Thanks for the advice all.

Solvol Autosol is what to use between the sand/emery paper to give a better finish before the lacquer stage. Have fixed lots of scuffs, chips etc this way and for 6 years old still look not too bad.

Thats a good tip. Never thought of that. Need to do a repair to 1 of my wheels. Will try that.
