I'm not convinced that repairing the gel-coat is critical unless the damage extends beyond that which is hidden by the window and glazing. I'd just use silica filled epoxy. Scrub it well to remove the amine blush and then maybe give it a little tooth by sanding it dull. The typical 80 grit might be a little much but just remove the shine.
