Proven solutions for rockchips?
I've got quite a few on my black 997, a few even managed to get on the upper hood near the Porsche crest.
I'd like to clean it up a bit. What are the options to do this? What kind of costs?
Thanks in advance.

Langka (sp) and Dr. Colorchip have products, but they require some practice and nerve (to leave blobs of paint on your car) to work well. Respray and then clearbra are more expensive options - just wait 30 days in between.

Dr. Color Chip I've tried without the best success, yet. It may be a temperature thing. Will try again with warmer temps and see if I can get a good product. The promotional videos look great.

I've used both with some success on various vehicles, but experience is the key.
I often use artist brushes (very narrow point) rather than the stuff supplied. Make sure there is no wax on the chip areas, get some 2000 grit, cut a small strip, put it in water. Soak well. Will use later.
Get some of the paint on the tip of the brush (no blobs, drips) and let it gently move into the chip. Wait about 15 minutes and do again. If you have the patience (key), do this about 6-8 times until the chip is built up enough.
Let sit.
Repeat. Yep, repeat.
As the paint builds and dries, there is less likely chance of blobs. You can either leave it level, or build up slightly.
If you build up above the plane of the existing paint, let it go for a week.
Clean after a week. Get the 2000 grit wet sandpaper and gently go over the blob. It helps to wrap this on a firm surface (paint stick for example) so you are going flat with the paint/surface. Do NOT get a piece of sandpaper so large - just a small bit will do.
After gently rubbing down the blob a bit, you will then need to come back with polish (various grits depending on surface condition). I usually start with #2, then #3, then #4....then hand glaze, then Rejex.
When you're done, it should be 90% or better.
If you are really uncertain about this, go to a salvage yard and grab an old sheetmetal part from a car at least 10 years old and experiment.
Beyond having good paint and good clean conditions, experience and patience are the keys.
Good luck.

Quick and dirty solution, that is not 100% but noticeably better is Turtle Wax Color Magic Black. Its basically a wax with black die. On my car I could see the road rash at 20 feet, after the color magic, I have to stick my nose about 2 feet away from the panel before I notice the rash.

Thanks gents, i'll see about these options when I get back. Might have a professional apply the quick solutions to be safe.
Appreciate it.

+1 for Langka. If you use it along with OEM black factory paint you should be able to get a very good result. If you use two or three applications you can achieve an excellent result. If you have lots of chips that may be too time consuming.
