In a small mixing bowl, stir together the seasoned salt, chili powder, garlic powder, pepper, and flour. Remove and discard the skin from the wings (if you weren't able to find skinless drumettes). Dip each wing into the seasoning mixture, pressing the mixture onto the chicken to coat well. Generously coat a large nonstick skillet with canola cooking spray and place over medium-high heat. Add the chicken wings (cooking in batches if necessary) and cook for about 4 minutes, or until the bottoms are browned. Flip with prongs and cook for about 4 minutes more. Reduce the heat to medium-low and add the beer. Cover the pan and cook for about 5 minutes. If the wings aren't cooked through, turn them over and cook for a few minutes more. Remove from the heat and serve hot with light blue cheese dressing if desired (not included in nutrition information below).
