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...

Had the same problem 5 years ago...after trying to stop the crack and using Eternabond, the crack finally went far enough to move from under the Eternabond, so I replaced it with one from EZ Tops...the original dome was screwed down too tight...cleaned the area under the dome, put in new decor sealer, drilled holes in the new dome, installed with new stainless screws ( not too tight), and put new Eternabond around the perimeter over the screws...no leaks now for 5 years.
