I tried correcting this scratch with 3d One and a cutting pad. The area is now completely smooth but the scratch is still visible. Is there anything that can fix this besides wet sanding. Is the problem that all the paint was just taken off with the scratch? Is there anything that can fix this besides wet sanding. I should also mention that this is audi paint which is supposed to be hard.

I'm not familiar with 3D One, but you might try a more aggressive compound like Menzerna 400 and then work your way up to a finishing polish to perfect the finish. What type of "cutting pad" did you use?

Those scratches look pretty deep. If you run your fingernail along the area does it catch on any of the scratches? It might feel smooth to your fingertips.
 
I had something similar on my wife's Buick after I detailed it and discovered someone had hit her rear bumper in the winter at some point. I ended up wet-sanding with 800-3000 grit, then using Meguires 105 and 205 compound and polish with Lake Country blue and orange foam pads to take it out.
 
Based on just what I can see, I'm thinking that's way too deep and if you keep trying to fix it you'll go through the clear in surrounding area.
As asked above, does your fingernail catch on it?

Exactly. I can still catch my nail on the deep scratches on my wife's Buick. I knew from other painting experience I didn't have much to work with so I made it look the best I could without burning through the clear. To ultimately fix her bumper it needs a repaint.
 
Just a random thought. That piece set in the bumper is the headlight washer cover, correct? Can you order that part pre-painted from Audi? While it wouldn't solve the problem of the scratches on the bumper it would at least get rid of the worst damage and may be cheaper than going to a body shop for a re-paint of the bumper.
 
Not sure what model of car that is, but is there any chance the section you are working on is plastic?

Are you thinking it's bare plastic? The second picture shows a glimpse of the bottom of the headlight, so I think we're looking at an area which is painted/clear coated plastic to match the entire car.
 
Here's one of the pictures so it's easier for everyone to see.... :picture:

Here's what I do for defects like this,

Take a 3" 3M Trizact #5000 sanding disc, or #3000 sanding disc if you have good skills, a little expereince and are feeling like living on the edge of a razor blade, then lightly sand against the scratches at about a 90 degree angle.

Then buff.

Right in the middle of the roof on this Porsche I detailed last weekend there was a bird dropping etching that had RAISED the paint, that is caused it to swell. This is a DANGEROUS type of defect to sand.

Around it were some HORRIBLE looking deeper scratches where some EXPERT thought they would rub some kind of compound over it to remove it. Both defects INSTANTLY caught your eyes.

I hand sanded with some #5000 grit and a little SONAX Glass Cleaner and then hit that spot with the BEAST with a LC orange foam hybrid cutting pad and some 3D ONE and after this - it was almost invisible. The only way you could find this defect is if you already knew where to look and had the right light to see it.

To echo Mike's comment, here are the before and after pictures of my wife's Buick Enclave bumper. Having prior experience doing custom painting, and as a production painter at work helped me know how far I could go living on that "razors edge". I knew full well that I wasn't going to get the entire bit of damage out, but I could at least take it from a visible 15 foot accident damage to a 2 foot inclusion. There is spider webbing and crazing still that won't come out, but you can see the before and after is a big improvement. I started out wet sanding with 800 through 3000 grit. Don't add muscle, just let the sandpaper do the work lightly. I then used my Flex 3" random orbit polisher with blue and orange Lake Country hydro tech pads and Meguires 105 and 205 compound and polish. I then topped it off with Wolfgang paint sealant.

No, I see that it is painted.
