Preheat oven to 400ºF, on convection setting, if you have it. Line two large, rimmed baking sheets with parchment paper and top with wire cooling racks. Oil the racks and arrange chicken wings in a single layer on top. Sprinkle evenly with salt. Bake wings for about 40 minutes, until skin is crispy.
Meanwhile, whisk together the hot pepper paste, honey, soy sauce, and garlic. Brush over the chicken wings and bake about 8 minutes more, until glaze is charring a bit in spots, watching closely toward the end. Sprinkle with sesame seeds and green onion, if desired.
