well if you can run you finger over the scratch and not feel it then your ok...but if it's through clear coat then there's not much you can do. If it's the first scenario then this is what you do...
1. Wetsand with 1000 grit paper. (let the sandpaper presoak for 10 minutes in water and keep the surface wet while sanding)
2. Wetsand with 2000 grit paper. same as above.
3. Use a clear coat safe cleaner...I use Meguiars.
4. Buff, buff, buff.
5. Use some kind of paint polish...again I use the Meguiars.
