Heat 2-3" of oil in a deep fryer or Dutch oven.
Working in batches if needed, deep-fry the wings 8-10 minutes or until done.
Remove to a paper towel-lined plate to drain. Transfer to a large resealable container or bowl.
Combine the tomato sauce, melted butter and hot sauce.
Add the sauce mixture to the wings. Toss to coat.
Let wings stand for 15 minutes.
Remove the wings from the sauce and transfer to another container.
Cover and refrigerate 8-12 hours.
Preheat oven to 350 F.
Spray a 9" x 13" baking dish with non-stick spray.
Spread wings out in the dish, cover with aluminum foil, and bake for 30 minutes or until hot.
Remove foil and bake another 5 minutes.
