I have a ~1 inch crack from a middle edge up. Anyone fixed a small crack with success? I’m thinking drill a hole at the top of the crack to stop it and cover it with lap sealant.
I had a crack on the sky light over the shower and I drilled a small hole at the top of the crack, covered the crack with silicone then covered that with a piece of Eternabond tape. Been over a year and so far so good. :)
