Can you catch the scratch with your fingernail? If it just barely does, you could polish it out to almost nothing. If it is deep, it will need to be painted.
Never heard of Dr. Chip, however if you get some OEM paint, you can dap it in the crevice witha toothpick or a very very small artist brush. There will be high spots. Then, you will need to wetsand with 2500 grit followed by 3000 grit. You will then need a machine polisher topolish out the sanding marks.
You could go with 2000, however I would try the 2500 first. Go in an up and down patterm very easy and keep the paint WET. Inspect your work. If happy, use 3000 and go left to right. Inspect your work. THe different directions help you see if you have removed all the lower grade sanding marks. Once you are happy with the feel, you will need to use a polish that is aggressive enough to remove those marks. You will need like a Meguiars
m105, Adams Swirl & Haze Remover etc. That will need to be followed by a finish polish and a wax. After all that, I highly doubt you will see it.
Word of advice when painting that scratch, go very light and use multiple applications to build up the paint. If you glob on with the applicator it comes with you will have a mess on your hands.
Hope that helps!
