Yeah, sorry. My Pokémon brain is kinda hard-wired to VGC (doubles), where everything has Protect. Here are some alternatives:
Aqua Tail, Thunder Fang, Dragon Claw
If you want support moves:
Tailwind, Defog, Stealth Rock
If this Aero is for Doubles, you could use any of the above moves, as well as the following:
Protect, Wide Guard
I hope this helps!
