I would not sand the scratch out, I would fill it with spot putty and
then  sand, prime and paint. You might want to get one of those small
guns or a preval spray for this. Be sure to ask your paint supplier
for a chemically compatible system, and be sure you have the correct
ratios and components for reducer, hardener, etc.  I have them write
it on the caps with a sharpie, and remember what goes with what
product.
