Sherwin-Williams Paint stores can match any color with you bringing in some parts off your car or drive it there and they can use their device to photo it, then see what their computer shows. I don't know if my spelling of the paint place is correct, but close enough. I know, in Texas, they are everywhere and sell really good quality paints. I got some to match past cars, in a spray can and cost me $15 for one spray can, but that was cheaper than having some paint shop try to match and paint the rock chip. Fiberglass is easy to work with. My gel coat on my CMC is not pretty and I will try the 1500 sandpaper, maybe, after some buffing with light buffing compound. They sell that as O'Reilly stores and it comes in different grids or grinds , depends on how bad he paint is. My the way, if anyone followed my past rant about my new purchase of this unfinished speedster kit, it was advertised as Fibefab, but decal on the firewall inside the front hood by gas tank area, clearly shows the CMC label. The man had no idea what he was selling. Brand makes little difference to me. It's an old body, never finished and seems rather thick on the fiberglass. There are some small surface star cracks, but I think I can fix those. Yes, matching up old paint , you need the latest computer system. O'Reilly auto parts also can do a match with a sample of your car's body. They can come out to your car, in the parking lot and use their device to get somewhat close to matching up the color. Modern tech stuff, just amazing. I stay far away from pickup trucks, construction trailers, dump trucks and garbage trucks. But, one day a small stone flew from across the highway, some fifty or more feet from my car and I watched it hit my windshield on another car I owned at the time and you feel so powerless and cannot move out of the way, to avoid that "tossed" stone. Right in front of driver's view and scared me. I now stay away from the inside or fast lane, due to that one event. Take the hood off and bring it to the repair shop, really good suggestion. I had some touch up done recently on my non-kit car and they kept the car in their dirty paint and body shop for one week. Even with a wash job, there was body dust everywhere I am still cleaning from the interior and other areas of that car. Body shops are dirty places. Good luck with the chip repair. I like the idea of keeping the paint close to the gel coat color. If you get a chip in the paint job, under it, is about the same color.
