You can buy gelcoat repair kits. My old man used one to repair chips in the front of his boat from the anchor. You cant see the repair at all, but i
dont know if that would be the same for a panel.
The kit comes with a syringe and all the bits you need to repair. I think it comes in white as standard, so you might need to get the pigment to
colour it to match, but it will be difficult to match it before it sets in the pot!
Kindest Regards,
Richard.

pigment is just the colouring for the gel. Like food dye.
The easiest way would be to fill the scratch withe new gel coat the same colour as your bodywork, using some pigment.
Then sand it back flush and polish.
Gel coat will not dry in air so you will have to use flow coat, add in some wax solution which forms an air barrier over the gel allowing it to set or
apply a polythene over the repair to allow the gel to set fully.
Then sand it back with fine grade paper and polish.

It does set, it's just the surface stays tacky. Cellotape over the gel keeps the air out just as well and it peels off nicely.

thats what I mean, set in air. All the other surfaces of the scratch wont have air present so will fully set.
