Product For Sealing Gap Between Steel Sheet and Bricks/Pointing

[novaf4]

I need a product recommended to me that comes in a cartridge (silicone? caulk?..) that Toolstation, Screwfix or B&Q sells, that will work around the perimeter of a mild steel sheet that has been screwed over a large hole in a brick wall. So, the product needs to seal the irregular but small gap where the steel sheet meets the bricks and indented pointing.

It doesn't need to 'bond', or be flexible, or be waterproof.

The location is an outside wall but 'housed' inside a brick-built potting shed.

Thanks.

I've used bolt resin on steel and brick. It's rock hard.

Other option is clear polymer mastic like stixall. Masking on steel and wall to Keep clean leaving a gap where you can apply mastic , then pull tapes when done
