Crack in gel coat

[Rockinfigs]

Hi I have a hairline crack in on the side of my hauler.. Little larger than a hairline but it's pretty thin.. What's the best way to seal it.. I was think of just putting some clear Chaulk and working it in with my finger so no water gets in it. Any suggestions

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.

OK.. That doesn't help me with my question

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

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

allow to harden, buff as require.

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