GTA Engine Bay

My GTA atmo has a small amount of corrosion on the bulkhead/firewall. I was planning to rub the rust off with wire wool and then paint over with 'Smoothrite'. Should I be using the 'Smoothrite' or is there something specific for use in a high temperature area like a GTAs engine bay!?

Hi Andy, most just use regular matt black spray as per original. So nothing fancy.
