I have a chip out of the gelcoat on the bottom of my boat where a stick drug up between trailer when loading. I sealed with silicone as soon as I got home & it doesn't leak. What do I need to repair this with??? There are also a few scuffs around bottom of sides of hull that I wouldnt care to touchup also. The hole in bottom is about 1.5 inches around. Fiberglass is in great shape. Hull is grey in color. Also wouldn't care to bring back the shine to topcap. It's a little faded & looking for a cost expensive way to bring the shine back as it is only in a few places that it's dull. Thanks
