I also use a comb. I spray paint my eyes with a white Krylon primer first. I then spray with Krylon fluorescent, green yellow,red, or orange. You can use two colors, one on the top of the dumbbell and another on the bottom. After it dries I use a black dot for the eye, using a small nail or drill bit. I then over spray with Krylon crystal clear.
