Preheat the oven to 400 degrees. Drizzle the oil on the baking sheet and spread it evenly over its surface.
Combine the flour, garlic powder, black pepper, and sea salt, to taste in a large Ziplock bag; seal and mix until well combined. Add a large handful of wings to the flour mixture and toss until evenly coated.
Remove from the flour shaking excess off; place skin side UP on the prepared baking sheet without crowding them too much. Repeat with the remaining wings. Discard any leftover flour.
Place the wings into the oven and bake undisturbed for 30 minutes. After 30 minutes, flip the wings over and continue to bake for another 15 minutes.
Remove from the oven and place on paper towels to drain grease.
Place the wings in a large bowl, drizzle the barbecue sauce on the wings, and toss to coat evenly. Serve immediately. Enjoy.
