How do I fix a crack in a poly skylight ?
I have a crack that leaks in heavy rain storms, in an outer roof top sky light, and have tried over and over to seal it. Usually after the next long trip, the crack extends itself. Is there any...

I drilled a small hole at the end of the crack and sealed with proflex then put a strip of eternabond over that. That was 2 years ago and still leak proof. :)
