Hardest part will be matching the color. If "pretty close" is good enough, that's no harder than repairing drywall. While Ronnie's advice is likely dead-on. You could easily fill sand repeat w/o needing to spray. I filled a nice "learning gauge" on my boat and i have a tough time finding it. To me... that's "pretty good".
One thing to remember, the gell coat ON your boat has likely faded a bit so don't be surprised if the repaired (and surrounding) area is a bit darker than the rest of the hull.
