Black duct tape? There are vinyl repair kits that have multiple colours in it but basically you mix to get the tint you want, if it's black you need it makes it easy. You apply. heat with iron and the metal tool (comes with different texture papers) to cure. I have used to to cover a few worn through spots on the trunk vinyl pieces stipple with my finger to good effect but I have my doubts it would stand up to the tension a top is under but failing anything else might be worth a try as they aren't expensive (at least mine wasn't).
