Crack in gel coat

You may need to drill some small holes on each end of the crack, so it doesn't spread.

OK but what's the best way to seal it

More gelcoat, Clean all wax off the surface, then squeegee some thinned gelcoat into the crack.

allow to harden, buff as require.

The walls are material called Filon, not gel coat.

Replace the whole sheet of Filon ($$$$). I would be more worried about WHY it cracked.

I would get a can of automotive clear coat. Mask it off to just expose the crack and spray away. If it’s a small crack you want something fairly liquid to fill the crack. The caulk may also work but I would be afraid it would attract dirt and look bad. A body guy told me the least intrusive method would be to give it a good coat of automotive wax. Of course it would have to be touched up from time to time.
