    ******. Reversing out of a tight spot. Cheers considerate neighbour and his van and in doing so my wheel slipped off parralel down off kerb and it got scratched

    They are diamond cut. Really peeved off with myself

    First mark I have had on the alloys

    Can these be repaired at home or do I need a professional. If so what is likely cost

    I think a photo would be useful to see the extent of damage.

    Is there any lacquer I can apply in the meantime as I assume as winter is coming that this may cause corrosion

    If it's minor like that you can, carefully smooth the chewed rim back with 180 grade wet n dry paper followed by 360 and finally with 1200 grade which gives something similar to the original finish - then put some clear coat on the bare metal. Don't work with full sheets of the abrasive paper, tear small bits off and work slowly, don't rush or extend the area of damage, with patience it will end up looking massively better. Mercifully I only did it once on the black 20" Rotors on the RSQ3, but did make the fix invisible.

    If you don't feel confident about doing it yourself then a professional repair would probably need the wheel to be sent off, as it is diamond cut. Cost is around £125-£150..

    Here is a clearer daylight pic. Will get some suggested sanding paper and give it a go I wonder if a dremel could be used 20181108_081927.jpg

    Dremel - probably, trouble with power tools is that stuff happens and goes wrong fast. You are working with a really soft material here, going slowly and carefully is the key and even by hand 15 minutes would suffice.

    cheers everyone

    there seems conflicting views on the starting grit to be used. Some say 600 - some say lower.

    The higher the grit the finer the finish.

    I would attempt to get it smooth and even with hand files for metal or even files for finger nails. Gives you a lot of control and will get nice flat surfaces and sharp angles. After that finish with very fine sandpaper.

    Definately do able - you won't get it perfect doing a DIY, but good enough from a distance. I've done a couple on my S4 (bl**dy tight French car parks!) and about 10 on the wife's car

    If you've got standard S4 alloys they're part diamond cut and part painted - obviously painted bits will need touch up paint (or spray if you're ambitious).

    My method is similar to above using tiny pieces of wet paper - I start with 120 grit to get the worst out, then 400, 800, and finish with metal polish. Clean thoroughly then paint/lacquer. Be careful to only sand the damaged parts - tiny bits of paper and slow movements are best. Forget power tools - far higher risk of making things worse and doing it by hand doesn't take that long anyway (soft metal).

    Personally I wouldn't bother paying for a refurb unless I'm selling the car. Sod's law dictates I'd go and kerb the wheel again within a week (friend of mine did exactly that)!

    I had my Volvo V60 diamond cut alloy kerb rash professionally repaired for just £60, I had to take the wheel to him when he was quiet. He took about 90 mins to repair it and you couldn't tell it had been damaged. Worth asking around the mobile repairers.

    decided to try and fix it myself and when i am close to selling the car then i will get them done as i am sure there will be other marks on the alloys by then

    Careful it could get worse as you don’t want corrosion to set in. Keep an eye on it.
