Place the turkey wing pieces into a large container. Season the wings with 1 tbsp poultry seasoning, minced garlic, and onion wedges. Pour the buttermilk all over the turkey, and let brine over night, for 8 hours.
Drain the wings, and discard the buttermilk. Rinse the wings under water, then set aside.
In a large bowl add the all purpose flour, 1 tbsp poultry seasoning, paprika, garlic powder, onion powder, ground black pepper, and seasoning salt. Sift ingredients.
Coat the wings with the seasoned flour.
Heat the oil until it reaches approximately 360 F, then slowly drop the wings into the oil.
Fry the wings until golden brown and completely cooked.
Place the wings on a paper towel lined plate to absorb any excess oil.
