I'd prolly get a Pre-Val sprayer and wipe it down really well with some acetone, tape it off, and spray it.

Will it spray thick enough to fill in and sand down to buff?
Will I need wax additive?

One of our former PRO members, used the Pre-Val spray system all the time to do these kinds of repairs. You have to thin the Gelcoat just a bit but for scratches like this it's kind of a good thing to lay down multiple thin layers in order to blend it all in with the other. Don't think you'll need any wax and you won't need much more than a patch kit to do the job. Just a few oz of gel should do the trick. getting it to match the exact color is the biggest trick of all. If the scratches are kinda deep, you should mix up some gelcoat paste by adding some cabosil with the gelcoat first to fill em in and then wet sand em down smooth then use the spray to blend it all in.

This should be of some help...http://store.preval.com/blogs/how-to/7827525-how-to-gelcoat-a-boat-with-the-preval-sprayer

Short term get a black sharpie and color it in, it will be far less noticeable.

The problem with black is it will stick out like a sore thumb once you do anything to that spot. The normal method if it was too deep to just sand out would be to clean out the scratch, sand out a few inches with 220 grit, use a tooth pick or very small artists brush to fill the groove with gel coat, then spray over it. Once cured, sand and buff. What you will probably find is that the hull has discolored and the new black doesn't match, and after buffing even the original gel coat won't match the surrounding area, so you end up buffing the entire hull to see if you can get it to blend in, the actual repair still won't match though. Sometimes people just live with the sharpie repair or fingernail polish. The sharpie or fingernail polish can easily be removed at anytime in the future when you decide how you want to proceed
