Small ding repaint

Did a bit of searching, and all the results contain information on how to paint and prep a car, not smaller dings.

What happened is I have a Black Widow kit on. I took it down a driveway, one that’s really angled, and the front bumper has 2 round like dings. What should I use on them? They’re kind of underneath the bumper, but they’re right on the edge of the bumper, so it can be seen straight on. The car is black, so should I just use some of that color match paint that comes in a little bottle for like 4 bucks? Or how else can I do it so it looks okay, without a repaint, since I just got it from the body shop painted three months ago.

Any advice would be appreciated.

PS. This makes me wonder how many more driveways I won’t clear when I actually lower my car.
