Butyl tape or sealant? They're not the same thing.
BUTYL TAPE goes between two pieces of metal that overlap. It sits inside the joint, gets squashed flat when the panels go together, and never dries hard.
That's the point of it. Metal expands and shrinks as the temperature changes, and the tape moves with it instead of cracking.
One rule: butyl has to stay hidden. Sunlight breaks it down, so it's not for anywhere it'll sit in the sun.
SEALANT is the one in a tube, for the joints you can see panel ends, flashings, around pipes. It dries hard, handles the weather, and ours comes in over 14 colours so it blends into the panel.
Use the wrong one in the wrong spot and you'll be back at that joint sooner than you'd like.
Whatever you're working on, follow the instructions that came with your panels.
