Minor hull repair/Downhaul Question

Hi all, first question
After hauling my DSII out last weekend I noticed a small chip in the hull near the centerline, no bigger than 1/8" but it's through the gelcoat and I can just barely see F/G. I'm going to be going back out on the water for a few weeks still though. This fall I plan to strip the old anti-fouling and re-apply. Is there anything anyone can suggest for a temporary repair, since it's getting new antifouling I suppose I don't need to match the gelcoat.
My second question is about the downhaul. I have both a grommet near the tack of the sail AND an eyestrap on the gooseneck. I've been using the gooseneck fitting. What is more effective? And assuming someone says the tack grommet, how would I lash it? bowline to the downhaul cleat?
Thanks again to everyone who helps us newbs!
