It appears that you need some wet sanding this should be done by someone that knows what they are doing....Have a look for a good detailer in your area....your local BMW dealer might have a source for you.....polishing might work but its going to be with a rotary buffer and an aggressive product to get the out.....real looks like its a bit deeper than that
It's got too much depth to fix with scratchX or really any polishing compound, from the looks of it.
Now, I don't guarantee any results with this method, but I've fixed a couple of scratches like that with touch-up paint, careful wet-sanding, followed by polishing. You want to use the tip of a toothpick and apply no more paint than you absolutely need to fill the scratch, then let it cure a few days. Follow up with some 2000 grit sandpaper to get it level, then use the polishing compound to remove the scratches.
If you're not confident of your ability to try this without screwing up your car, a good detailer can take care of it.
Thanks, actually the scratch looks bigger in the pics than in reality since I did a pretty big zoom on it. I painted the scratch last night and am now waiting for the paint to dry.
I'll get started on practicing the wetsanding thing on my old bumper. Thanks all for your replies.
