Preheat grill to 350° to 400° (medium-high). Cut the chicken wings at the joint separating the wingette from the drumette and remove the wing tips. Place wings in a large mixing bowl and toss with olive oil and Pork Barrel BBQ All-American Spice Rub. Place the wings over direct heat and grill for 4 minutes or until golden brown and flip and cook for 4 minutes or until golden brown. Move wings to indirect heat and cook for an additional 10 minutes or until done. Placed grilled wings in a large mixing bowl and pour ½ to 1 bottle of hot sauce (depending on how hot you want them) over the wings and toss to coat wings thoroughly with hot sauce.
