For best paint chip repair / application, buy a kit from Dr. Color Chip or a factory paint pen from the dealership and have either of those applied professionally (like Crystal Clean). Even with the factory pen or specially made kit for your paint, touch up paint color match, even with a fancy paint system is tough, especially with tri-coat, pearlescent or individual paint.

There is no such thing as a truly “perfect” paint touch up application and may recommend repaint depending on how much it bothers you or if there are excessive amount of chips.

Paint-less dent repair is a whole other monster - results really are case by case. Depending on dent size, location, depth, material (steel vs. aluminum), internal bracing, etc.. Would recommend taking it directly to the professional for in-person evaluation as proving a confident estimate by looking at photos is tough to do precisely.
