Rub all sides of the pork with the seasoned salt and lemon pepper seasoning. Put the rib sections on the grill. Prepare Fred’s Special Spray by mixing the lemon juice, vinegar, and Worcestershire sauce. Put this mixture in a food-safe spray bottle. Spray the ribs with Fred’s Special Spray. Cook the ribs until they are browned, about 1½ hours, spraying often with the sauce. Put the ribs in a 4-inch-deep stainless-steel pan with a lid. Spray the ribs once more and close the lid completely. Increase the grill temperature to 300°F and cook the covered ribs for 3 hours more.
