It really sounds like I’ve been corrected twice by the same information so...

GELCOATS

There are two main types of gel coats- general-purpose gel coat and tooling gel coat. Both are polyester resins that use MEKP as the catalyst. General-purpose gel coat is softer and more flexible than tooling gel coat. It will flex and not crack under constant vibration. Tooling gel coat is harder and does not scratch as easy as a general-purpose gel coat. This makes it ideal for molds that will be used many times. Gel coat comes in a wide variety of colors. We can even color match.

It is recommended to spray the gel coat. It will need to be thinned with styrene monomer before spraying. It is possible to brush on gel coat but the finish will be far superior if it is sprayed on.

The crap you paint on top has wax

Go see a glassman. Don’t try to extract info from forum debate. You can’t expose gel coat to oxygen during cure period. It’s why there are two types not some special experience. One for moulds one for topical repairs including vacuumed bagged. Swap them and you’ll have a glazed or cracked gel. You tube the gel coat companies.
Here’s one site

One to make laymen experts

The folks who think the wax stuff is for moulds burn the moulds and warp the part. The wax in the mould is a release spray and has nothing to do with the gel either than completing and oxygen free set area.
The cleaning spray completes the cure set strips the wax off done outside and away from the mould.
You didn’t share enough photos this time to give us a feel for the area. Maybe a moulded insert with an interior truss is you best repair. A dramatic bevel edge and a “V trough top and bottom to bond. It may be easier than a patch. A mould is easier to work and the other reason I brought up the two gel coats specific purpose.

Here’s a web site to match up your non slip surface. Before my Jeanneau I had several SeaRays. This is the pattern for a 270 300 310 cockpit. Lay the sheet down on maple plywood good one side. You can get male or female sheets 4 feet wide max.

You can use finish gelcoat, on exterior too, the wax floats to the surface after spraying or brushing and finishes the cure.
You cannot laminate to gel that has wax in it. One is a much more water proof type of resin.
The shine comes from sanding and buffing it out, as they both are kinda dull when cured.
