How to get rid of curb rash?

I got axis penta's with chrome/polished lip. Few days ago I hit the curb in a drive-thru trying to avoid a huge pot hole!
Now I got a 3" long curb rash on the very tip of the lip. The rash is around 1/2" in height but 3" long.
Is there a way to get rid of curb rashes?? Can I get one of those very light steel wool and try to buff it out??

I'll post pics tomorrow.
Thanks.

Stop hitting curbs is the best way to get rid of it....

Post pics, impossible to suggest unless you know how deep it is.

chrome/polished lip you will likely not be able to repair it yourself and will have to pay a bit to have it fixed, but post pics to see how severe it really is

Finally got the chance to post some pics of my curb rash on my new rims.



What do you guys think??
The rash isnt that deep but around 3 inches long.. Is there a way I could try to buff out the rash with some light steel wool?? without damaging the chrome/polish finish??

I take care of my rashes with a bit of gold bond and some TLC.

Looks like you can start with a file to smooth down the roughness. Then follow it up w/ wet sand paper. Start out with 400, 800, 1000 then finish it up w/ 1500 to 2000. Then finish it up w/ aluminum polish. Should make it alot less noticeable.
GL!

everyone on caswell seems to say anything more than 600 grit on aluminium is overkill. They all go 80, 150, 240, 360, 4**, 600, then straight to polish

You can use whatever grit you like. The higher grit count = the less effort you have to put into polish to eliminate scratch marks. If the wheels are highly polished, you'll want to up the grit count (maybe 2000 is overkill, but IMO, 1000 and 1500 are not), to aid the polishing, especially if you're doing it by hand.

Edit: I looked at the Caswell's site on buffing/polishing. They are following up the 600 w/ polishing compounds which have abrasive properties (hence the different types of compounds they offer) to reduce scratches after sanding. This is what your higher cound wet sand will accomplish, as well. Either way would be fine, you can usually get an assortment pack of wet sand paper to save a little money versus purchasing different grades of polishing compound to complete the job.

Good info though:

This doesn't look bad at all, starting with 80 is going to do more harm than good.

Start as high as you can to see if you can clean it up without taking off too much metal. This is one of those measure twice cut once.... but you can't measure so inch towards it best you can.

You might be able to make it look fair using methods mentioned by member above but if you want it to disappear find a wheel repair shop in your area and have it done right. Small rash like that shouldn't cost you too much....

that's why you have to use polishing compound to buff out the sanding scratches

go get yourself an aluminum polishing set from harbour freight, it's on sale right now for $15
