Paint Chipping - touch up pen?

2015 Mazda 6
Hey everyone,
(2015 Mazda 6 white)

Just washed my car for the 1st time after a couple months of Toronto winter.
Im now seeing quite a bit of tiny chipping along the hood, most likely from rocks on the highway.

Anyone have experience with the touch-up pen from Mazda?
Does it work and does it look good?
Any other remedies?

I have used the touch-up pen with excellent results. I use A2N "Performance White" and the pen allows you to squeeze the container in order to add a larger bleb or even to be used with the tip pointed up.

Get it.
