If the scratch is about 2 years old, you may soon have issues with rust. I used the following for fixing chips and scratches on my car, results were good. If you take your time and follow the directions exactly you could get great results. With such a long scratch you will have to sand, prime, sand, prime again, sand, and spray paint to blend. Despite the accuracy of the touch up paint, if you use a small tipped brush applicator, the repair would likely look like pin stripping due to the type of scratch, variation in depth, and sun/environmental effects on the existing paint.

If you never worked with automotive paint, I would get a can of cheap spray paint and practice painting a pieces of smooth scrap plastic, (5 gallon bucket) to get used to painting contours, preventing drips, and "feathering" the new paint to existing for a seamless transition. Then try a little of the spray touchup paint on a hidden part of the car to compare against the existing paint color. Make sure to cover the non-affected area with lots of news paper and paint on a calm day to prevent drift and waves in the paint.
