Eternabond Failure

That surface cracking is only cosmetic since the actual sealing is from the microsealant and IMO any water issues are most likely due to improper uniform sealing because folks want to slap the Ethernabond on top of bulky uneven caulking. It is critical that you have uniform adhesion and the normal roof seal is not made for anything but smooth surfaces ... there is a thicker microsealant version of the roof seal that is made for better adhesion on minor non smooth surfaces, but all that only goes so far. That top white layer is for UV protection and to prevent dirt/debris from adhering to the microsealant. If you remove the white layer you basically have what is the webseal version of Eternabond that needs to be painted or covered with a sun protective layer for lasting sealing. I removed all the caulk prior to applying the Eternabond and now after 9+ years I'm just now starting to develop some cracking on the front roof to end cap seal. This I attribute this to it's continuous full exposure to the sun. I also sometimes wonder of folks are getting the real Eternabond when they buy stuff off the internet not realizing that there is a shelf life of something around 5 yrs for the actual Eternabond product.
