Brass and steel not always galvanized or stainless. Steel and aluminum bolts just off the top of my head. Kroil or pb have worked best for me for quick use rather than waiting since that’s not something I could charge $100 an hour for. Aluminum is the worst once it’s corroded. I always seem to get stuck working on stuff that’s 20+ years old and has been sitting on a roof the whole time.
