You can get an exact match of your gelcoat from mini-craft of Florida. they have gelcoat for seacraft by model year. I have shot gelcoat for small repairs using a Preval sprayer. I have used it with duratec, using 50% gelcoat and 50% duratec. I have also sprayed gelcoat thinned about 15 to 20% with styrene and 1% wax. Both worked out well. remember to sand and clean the area first, and spray from the center of your repair out. Spray light coats, let them flash a little and respray until you are satisfied with the thickness. Let dry, then, sand the repair carefully. wet a cloth with some acetone and spray some black lacquer on it and wipe it lightly over the repaired gelcoat. Sand with your coarsest paper (for small repairs I use 150 grit ) until you clear off the lacquer. Repeat the process using progessively finer grits, but make sure that all of the orange peel is gone before you get to to them. I typically use 150 or 180, 220, 400, 600 , 1000 and 1500 and finish up with compund and polish. The Preval sprayer, which you can buy at Home Depot for about $5, has worked well for me. I have also used an E&S 100 spraygun with a 3/16 tip for larger areas. I hope that this helps, and I wish you good luck with your repairs.
