Composite prop blade repair

I have an MT two-blade composite prop where I repaired a little nick in the trailing edge (cowl install mishap) about 25% of the length from the hub. Looks pretty much like attached, although not exactly. I mixed up the epoxy resin, then dyed it black then, then filled the damage. No problems with the repair, but sanding it smooth took some of the black paint down to the white base on some small parts of the propeller adjacent to the repair.

What paint should I use to bring it back to black? Epoxy vs acrylic enamel?
