Hi Dave.
If the scratch is just in the surface gel coat you can use some 1200 wet & dry paper ( wet) anf sand it out followed by some rubing compound polish ( Farecla G3). If the scratch has gone deeper that the top surface gel coat then you'll have to grind it out a bit to either take more gel coat or filler with paint. The latter course of action is best avoided if possible and maybe learning to live with the scratch is better.
