Need to fix cable hole in roof that is leaking. I guess hole was for old satellite dish.
eternabond
I agree with Trubojack... I understand why dicor is used in the industry but my personal opinion is that it's an inferior product. It'll eventually shrink and allow the leak again. If you don't want to re-glass it, I'd slap some eternabond on it and call it a day.
And, if the hole is larger and or several holes from where the satellite dish was mounted. Cut a piece of aluminum (any box store) large enough to cover the whole area. Paint one side white to match the roof and affix it to the roof. If small, you can use 3M 4000 or if larger, screws bedding them and the perimeter of the piece in any good polysulfide.
Agree on Eternabond for a small hole, but it gives no structural rigidity.
I use epoxy for small holes and fiber glass big holes and gel coat over the repairs so it look new.
Ken, I have mentioned this in previous threads. When I removed my old dish, I had a dozen holes to fill. I used PlasticAid. The stuff works great for fiberglass patching or holes. Just mix it up and let it drip into the small holes, or wait a few minutes for it to thicken and you can work it for larger holes.
I keep packages in the Coach and at home, it has many uses.

Thanks to all for the suggestions. I am trying a couple different ones to see what works for me.
