OP, If you want that like new look here are the steps to achieve it. I learned how to do this from a work mate who grew up doing body work. His dad owned a body and frame repair shop for over 30 years. He literally taught me the technique when I was too poor to afford to have a hood and two front fender areas resprayed due to multiple rock chips.
First thing hand wash and dry the affected area, use a soft bristle tooth brush to get into he chip spots. They have to be completely clean. Next hand dry the area.
Time to check the chip spots for rust. I like a jewelers loop for this. Check the chips for any rust. If you find rust a set of dental cleaning picks are small enough to scrape off the rust. Once the rust is gone treat those chips with a rust inhibitor.
Now you are ready to paint. This is also a technique I learned from the same guy. This article and video will show you the tool and technique to get the chips filled in properly.

Once the chips have all been filled and the paint is throughly dry you need to wet sand the chips. Small dowel rods with 1000, 2000, & 3000 grit wet sand paper cut into small pieces and glued onto the down rod tips work well. If the chips are small a paper hole punch can be useful for punching out small circles of sand paper.
Sand with progressively finer grit sand paper until the chips are smooth and level to the other paint. Once that is done clean the area again by hand with soap and water and throughly dry.
Time to clear coat the chip areas. After each application of clear coat you want to lightly sand with 3000 grit except for the final coat. Once you have applied the number of coats of clear coat comes the fun part.
One last wash of the entire hood in this case, again by hand and hand dried. Time to buff the hood out completely with buffing compound. This will blend the repaired areas with the rest of the hood. If you are careful and take your time you can fix those chipped areas so that you and anyone else will struggle to find them.
Most body shops don't do this as for them it is usually cheaper and faster to just respray the hood, then it is to do all of that work for just the chipped areas.
Good luck on your project no matter how you decide to go about it and do look to invest in one of the methods mentioned above to protect from any further damage.
